Identifying the slope, y-intercept and x- intercept of each
Answer:
slope= -3
y-intercept= 6
Step-by-step explanation:
1. Approach
To solve this problem, one needs the slope and the y-intercept. First, one will solve for the slope, using the given points, then input it into the equation of a line in slope-intercept form. The one can solve for the y-intercept.
2.Solve for the slope
The formula to find the slope of a line is;
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where (m) is the variable used to represent the slope.
Use the first two given points, and solve;
(1, 3), (2, 0)
Substitute in,
[tex]\frac{(0)-(3)}{(2)-(1)}[/tex]
Simplify;
[tex]\frac{-3}{1}\\\\=-3[/tex]
3. Put equation into slope-intercept form
The equation of a line in slope-intercept form is;
[tex]y = mx + b[/tex]
Where (m) is the slope, and (b) is the y-intercept.
Since one solved for the slope, substitute that in, then substitute in another point, and solve for the parameter (b).
[tex]y=-3x+b[/tex]
Substitute in point (3, -3)
[tex]-3=-3(3)+b\\-3 = -9 + b\\6 = b[/tex]

Solve the following system of equations using the SUBSTITUTION METHOD.
SHOW YOUR WORK for full points. Write your answer as an (x,y) point.
x=4y-1
x+2y=11
Answer:
x = 7, y = 2
Step-by-step explanation:
x= 4y -1
since x is by itself 4y-1 will substitute for x in the other equation x+2y=11
it will become 4y-1+2y=11
+1 +1
add one to both sides since is doesn't have a variable.
it will become 4y+2y= 12 now add 4y+2y
becomes 6y=12
_ _
6 6
divide by 6 on each side and you get y=2.
now x=4(2)-1 you will substitute y into the first equation.
x=8-1 subtract 8 from 1 to get 7.
x=7
y=2

The water treatment plant has a tank with a leak. The water tank is leaking at the rate show on the graph.
Find the rate of change at one of the two identified points
Answer:
the water is leaking at a rate of 3/4 a gallon per hour
Step-by-step explanation:
we know this because rate of change is change in y over change in x and as y goes up 3 x goes up 4 so the rate of change is 3/4

What is the slope of the line that passes through the points (-2,7) and (2, -5)?
Write your answer in simplest form.
Answer:
m=-3
Step-by-step explanation:
Answer:
-3
Step-by-step explanation:
Slope = Rise/Run
We can find the amount between 7 and -5 as 12, and -2 and 2 as 4.
Then we can do rise/run and 12/4
Which would divide into 3.
ANd because we can see the x increases as the y decreases, we can find that it's a negative slope.
-3
Tell whether each system of equations has no solution or ,infinitely many solutions.
Answer:
See below.
Step-by-step explanation:
x + 2 = x + 2 ⇒ Infinitely Many Solutions
3x + 1 = 3x - 10 ⇒ 1 ≠ -10 ⇒ No solutions
x + 4 = 2x + 4 ⇒ 4 = x + 4 ⇒ 0 = x ⇒ One solution

Answer:
the numerator is: 22
the denominator is : 30
___________________
the simplified numerator is: 11
the simplified denominator is: 15
Step-by-step explanation:
Answer: 22/30 reduced is 11/15
Step-by-step explanation: Half 22/30 to get 11/15, (so 22/2=11 and 30/2=15) Your numerator would be 11, and your denominator is 15.

{}Urgen{} Delta Math
Answer:
57°Step-by-step explanation:
Use the law of cosines:
cos F = (e² + g² - f²)/2egcos F = (2.6² + 8.3²- 7.2²)/2(2.6)(8.3) = 0.5516∠F = arccos 0.5516∠F = 57° (rounded to the nearest degree)Answer:
57
Step-by-step explanation:
cos F = (e² + g² - f²)/2eg
cos F = (2.6² + 8.3²- 7.2²)/2(2.6)(8.3)
= 0.5516
∠F = arccos 0.5516
∠F = 57° (rounded to the nearest degree)

Choose the two expressions that are equivalent to 5. 75 ÷ 1. 15
A: 575 ÷115
B: 5,750 ÷ 1,150
C: 5,750 ÷ 115
D: 575 ÷ 1,150
Answer:
A and B, but I’m gonna explain it the best I can too.
Step-by-step explanation:
5.75 divided by 1.15 is the same as answer A, since all you are doing is taking away the periods, making it whole numbers.
Again 5.75 divided by 1.15 is the same as B as well, Since it is the same just without the periods and an added zero at the end of each.
This Is so that they are both all equivalent by being whole numbers, but whatever you do to one numbers in the expression that you think is the answer you have to do to the other numbers in the expression
they have to add up completely the same.

x + 2y = 4
or
y= -3/4x - 1
To get both the X value and the Y value? I would really appreciate it loves <3
Answer:
your question is unclear
Step-by-step explanation:
x+2y=4
-x -x
2y=4-x
divide by 2 to get y by it's self
y=2-(1/2x)
x+2y=4
-2y -2y
x=4-2y
