Answer:
Your equation would be
y=4x-12
Step-by-step explanation:
So an easy way to figure this out is graph the points and look at the distance the points are away from each other. In this case it was 12 up and 3 right. This is your slope. Simplify the fraction to 4/1. Then from (2,-4) use the given slope to work back to a point that is on the y axis, which is (0,12). Plug all of the given information you found into y=mx+b and you get the given formula.
Answer: It is only 5 points, if it were 20 points, I would answer.

The point-slope equation is
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
m, the slope is -4/5
![y = - \frac{4}{5} x + b](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%5Cfrac%7B4%7D%7B5%7D%20x%20%2B%20b)
We plug in the point (3,-2) to find b:
![( - 2) = - \frac{4}{5}(3) + b \\ - 2 = - \frac{12}{5} + b \\ - \frac{10}{5} = - \frac{12}{5} + b](https://tex.z-dn.net/?f=%28%20-%202%29%20%3D%20%20-%20%20%5Cfrac%7B4%7D%7B5%7D%283%29%20%2B%20b%20%5C%5C%20%20-%202%20%3D%20%20-%20%20%5Cfrac%7B12%7D%7B5%7D%20%20%2B%20b%20%5C%5C%20%20-%20%20%5Cfrac%7B10%7D%7B5%7D%20%20%3D%20%20-%20%20%5Cfrac%7B12%7D%7B5%7D%20%20%2B%20b)
![\frac{2}{5} = b](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B5%7D%20%20%3D%20b)
We can now plug in b to the equation:
Answer:
False, FALSE, true
Step-by-step explanation:
Answer:
Write 0.72 as
0.72
1
Multiply both numerator and denominator by 10 for every number after the decimal point
0.72 × 100
1 × 100
=
72
100
Reducing the fraction gives
18
25
