Choose the best explanation for why the graph shown is a line of best fit.
The graph shows a line of best fit because the points fit around the line.
The graph shows a line of best fit because there is a straight line.
The graph shows a line of best fit because the association is zero.
The graph shows a line of best fit because the points are plotted evenly above and below the line.
Answer:
The graph shows a line of best fit because the points are plotted evenly above and below the line.
Step-by-step explanation:
The best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
We have a line of best fit shown in the picture.
As we know if the slope of the line is positive then the correlation will be positive.
From the line of best fit:
Because the points are evenly spaced above and below the line, the graph displays a line of best fit.
Thus, the best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.

Linda and Juan went shopping. Linda spent $15 less than Juan.
If we let
z represents how much Juan spent, write an algebraic expression for how much Linda spent.
Answer:
Linda = z - 15
Step-by-step explanation:
Linda spent $15 less than Juan, it means: Linda + 15 = z
Linda + 15 - 15 = z - 15
Linda = z - 15

At high school basketball game, the athletic department sold 250 tickets and brought in 837.50. Adult tickets cost $5 and student tickets cost $2.50. Write a system of equations for this situation.
Answer:
The system of equations is:
[tex]a+s = 250\\5a+2.50s = 837.50[/tex]
Here a is the number of adult tickets and s is the number of student tickets
Step-by-step explanation:
We will use the given statements to make a system of equations for the given scenario.
First of all we have to decide which variables to be used.
Let a be the number of adult tickets and
Let s be the number of student tickets
So according to the statement that the department sold 250 tickets in total, the equation will be:
[tex]a+s = 250[/tex]
This is equation one of the system of equations
According to the statement that cost of adult ticket is $5, total cost of adult tickets will be: [tex]5a[/tex]
According to the statement that cost of student ticket is $2.50, total cost of student tickets will be:[tex]2.50s[/tex]
The total earning was $837.50 so the second equation will be:
[tex]5a+2.50s = 837.50[/tex]
Hence,
The system of equations is:
[tex]a+s = 250\\5a+2.50s = 837.50[/tex]
Here a is the number of adult tickets and s is the number of student tickets

(-4,6); slope = -3/4
Answer:
y = - [tex]\frac{3}{4}[/tex] x + 3
Step-by-step explanation:
Assuming you require the equation of the line
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - [tex]\frac{3}{4}[/tex] , thus
y = - [tex]\frac{3}{4}[/tex] x + c ← is the partial equation
To find c substitute (- 4, 6) into the partial equation
6 = 3 + c ⇒ c = 6 - 3 = 3
y = - [tex]\frac{3}{4}[/tex] x + 3 ← equation of line
The equation of a line with given coordinate point and slope is y = -3/4 x + 3.
The given coordinate point is (-4, 6) and slope (m) = -3/4.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
Put, (x, y) = (-4, 6) and m=-3/4 in y=mx+c, we get
6 = -3/4 (-4) + c
⇒ 6 = 3 + c
⇒ c = 3
Substitute m=-3/4 and c=3 in y=mx+c, we get
y = -3/4 x + 3
Therefore, the equation of a line with given coordinate point and slope is y = -3/4 x + 3.

c. y = 0.8x
d. y = 1.2x
can someone try and provoide an explanation I really don't get this.
Answer:
B
Step-by-step explanation:
1/5 as a a decimal would be 0.20 because if you multiply 0.20 by 5 you get 1
Answer:
B
Step-by-step explanation:
First convert [tex]\frac{1}{5}[/tex] to a decimal : 0.2
y represents how many strawberries Zoe ate
x represents how many strawberries Nora ate
If you take the equation- y = 0.2x and plug how many strawberries Nora ate you would claculate how many Zoe ate.
For example: say Nora ate 10 strawberries the equation would be- y(how many strawberries Zoe ate) = 0.2 · 10 ( the naumber of strawberries Nora ate)

An online movie streaming plan charges an annual fee of $48 plus $2 per movie watched. Another plan has no annual dee but charges $4 per movie watched. For how many movies is the cost of the plans the same? *
write and solve
Answer:
24 movies
Step-by-step explanation:
48 is a constant. 2 and 4 are variables. So we write 48+2x=4x to show they are equal after some amount of movies. Isolate to get 4x-2x=48. Simplify to get 2x=48. Divide each side by 2 to get x=24. The answer is 24.

Answer:
-they are all straight lines
-they all cross the y-axis at (0,4)
Step-by-step explanation:
Answer:
All these graphs intercept the y-axis at 4 OR
All these graphs b = 4
All these graphs have a slope or are non-vertical
Step-by-step explanation:
y = 3x + 4
y = 2x + 4
y = -x +4
y = -5x + 4
All these graphs intercept the y-axis at 4
slope intercept equation is y = mx + b, the line intercepts the y-axis at b
In addition, all these graphs have a slope or are non-vertical

Encik Ahmad builds a rectangular shaped garden
measuring 85 m long and 30 m wide. He divides the
garden into square plots to plant a variety of flowers.
Find the number of square plots that can be built if he
only wants three different square sizes.
Answer:he should build them 25x10
Step-by-step explanation:
Encik Ahmad can build 10 square plots with three different sizes.
What is Rectangle?Rectangle is a polygon in two dimensional geometry which has four sides and four angles and each angle being right angles.
Length of the rectangular plot = 85 m
Width of the rectangular plot = 30 m
We have to find the number of square plots Encik Ahmad can built of three different sizes.
For that first we take a 45 m length of the plot.
Divide it to three equal lengths. We get three lengths with each 15 m length.
Along the width also, divide into two equal width, each having a width of 15 m.
Each 15 m length, we will get two square plots.
Along 45 m length, we get 3 × 2 = 6 square plots.
The remaining rectangle has length 40 m and width 30 m.
Divide this length as 30 m and 10 m.
So we get a square of dimension 30 m.
Remaining is a rectangle whose remaining length is 10 m and width 30 m.
Along the width, divide into three equal widths, each 10 m.
So there we get three square plots with side length 10 m.
So we have 10 square plots, 6 having the side length 15m, 1 having the side length 30 m and 3 having the side length 10 m.
Hence he get 10 square plots having three different sizes as 15 m, 30 m and 10 m.
