the required equation of the line is y = -3x + 8. option D is correct.
Given that,
To determine an equation of the line through (3, -1) and (−2, 14).
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m = tanx, where x is in degrees.
What is simplification?The process in computation to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Slopes of the line can be given as,
m = [y₂ - y₁ ] / [x₂ - x₁]
for points, (3, -1) and (−2, 14)
m = 14 + 1 / -2 - 3
m = -15 / 5
m = -3
So, equation D contains the slope -3.
Thus, the required equation of the line is y = -3x + 8. option D is correct.

Answer:
3/4 and 6/8
Step-by-step explanation:
The ruler is split into 8 parts, and this point is 6/8 of the ruler, if you simplify that fraction you get 3/4.
Answer:
3/4 and 12/16
Step-by-step explanation:
If you see there are 8 ticks. So it will go 1/8 to 8/8 or 1. Then you see the arrow is at 6/8. So you divide both by 2 to get 3/4 and multiply by 2 to get 12/16.

Look at the rectangle and the square:
A rectangle PQRS and square LMNO are drawn side by side. The length SR of the rectangle is labeled as 12 inches, and the width QR is labeled as 6 inches. The side LM of the square is labeled as 6 inches
Sam says that the length of diagonal SQ is two times the length of diagonal OM.
Is Sam correct? Justify your answer and show all your work. Your work should state the theorem you used to find the lengths of the diagonals.
Answer:
False
Step-by-step explanation:
Let's consider the triangle SQR. We know it is right-angle because part of the rectangle PQRS. We can use the Pythagorean theorem:
[tex]SQ^{2} = RQ^{2} + SR^{2} \\SQ^{2} = 36 + 144 = 180\\SQ = \sqrt{180} = 13,4[/tex]
We can do the same for the square in which ON = 6 because it's a square:
[tex]OM^{2} = MN^{2} + ON^{2} \\OM^{2} = 36 + 36 = 72\\OM = \sqrt{72} = 8.5[/tex]
Now let's compare them:
8.5 X 2 = 17 so OM X 2 is not equal to SQ
The sentence is false.

What is the y-intercept?
What is the x-intercept?
What is the slope of the line?
Find an equation for this line.
Answer:
Step-by-step explanation:
The "y intercept" is the point at which the graph intercepts the y-axis. In this case that point is (0, 20).
The "x intercept" is the point at which the graph intercepts the x-axis. In this case that point is (5, 0).
The slope of the line is m = rise / run. Here the "rise" is actually a drop from y = 20 to y = 0, so "rise" = -20. The "run" is the increase from x = 0 to x = 5, which is 5. Thus, m = the slope = -20/5 = -4. The slope is m = -4.
Given that we know the slope, m, of this line (m = -4) and two points on the line (use (0, 20) ), we can write the equation of the line immediately in point-slope form y - k = m(x - h), which in this particular case is
y - 20 = m(x - 0), or
y - 20 = -4x
Alternatively, we could put this into standard form: 4x + y = 20, or into
slope-intercept form: y = -4x + 20

Answer:
y= 1/4x
Step-by-step explanation:
A total of 76 students responded to a survey about transportation to school. Of the girls surveyed, 22 walk to school and 29 get a ride. Of the 25 boys surveyed, 9 get a ride to school. Construct a two-way frequency table to display the data. Drag the numbers into the boxes. Each number may be used once, more than once, or not at all.
Answers:
From as I can see. You need to do a long division on 76 and 9 and then if you got the answer subtract the answer with the girls surveyed and you'll get the answer and multiply the answer with the boys surveyed and then add all the answers together. Hoped this help!!! :)

The graph shows the prices of different numbers of bushels of corn at a store in the current year. The table shows the prices of different numbers of bushels of corn at the same store in the previous year.
A graph shows the Number of Bushels on the x-axis and the Price of Corn in dollars on the y-axis. The x-axis scale is shown from 0 to 14 at increments of 2, and the y-axis scale is shown from 0 to 98 at increments of 14. A straight line joins the ordered pairs 2, 14 and 4, 28 and 6, 42 and 8, 56 and 10, 70 and 12, 84.
Previous Year
Number of Bushels
Price of Corn (dollars)
2
10
4
20
6
30
8
40
Part A: Describe in words how you can find the rate of change of a bushel of corn in the current year, and find the value.
Part B: How many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? Show your work.
Answer:Part A:8 Part B:$1
Step-by-step explanation:
Part A: 7 dollars
- The graph shows that 2 bushels is 14 dollars, because the graph has a straight line, the rate remains constant you must divide the sides by two to find the amount for one bushel which would be 7 dollars.
- And to double check you would divide 28 by 4, 42 by 6, 56 by 8, 70 by 10, 84 by 11, and 98 by 12. they all equals 7 dollars So, the equation would be y = 7x.
- 7 can be known as the slope and rate of change.
Part B:2 dollars
- The years before show 2 bushes was 10 dollars
-so you would divide 10 by two you would get five To double check you would do the same thing with 20 by 4, 30 by 6 and 40 by 8, and they all equal 5 dollars.
-if you use this answer be sure to reword it so you dont get copy write and integrity. have a great day or night.

A candy bar costs $0.79
Find the price of the candy bar if it is sold with a 65% mark up
A. $1.58
B. $1.44
C. $1.30
D. $1.17
Answer:
C. $1.30
Step-by-step explanation:
Multiply 0.79 and 0.65 (65%) which is about 0.51.
Add that to 0.79.
Answer:
$ 1.30
Step-by-step explanation:
Increased price = 65% of $0.79
[tex]\frac{65}{100}*0.79[/tex]
= 0.65 * 0.79
= 0.5135
= $ 0.51
Selling price = 0.79 + 0.51 = $ 1. 30
