(-4,5)(-2,-3)
slope(m) = (y2 - y1) . (x2 - x1)
slope(m) = (-3-5) / (-2-(-4) = -8/2 = - 4
y = mx + b
slope(m) = -4
(-4,5)...x = -4 and y = 5
now we sub and find b, the y int
5 = -4(-4) + b
5 = 16 + b
5 - 16 = b
-11 = b
equation is : y = -4x - 11
Answer:

Step-by-step explanation:
Mark any two point on the line
(-1 , 0) & (-3 , -1)
Slope = 
![= \frac{-1-0}{-3-[-1]}\\\\= \frac{-1}{-3+1}\\\\= \frac{-1}{-2}\\\\= \frac{1}{2}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B-1-0%7D%7B-3-%5B-1%5D%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B-1%7D%7B-3%2B1%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B-1%7D%7B-2%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B1%7D%7B2%7D)
m = 1/2 ; (-1 , 0)
Equation: 
![y - 0 = \frac{1}{2}(x - [-1])\\\\y = \frac{1}{2}(x + 1)\\\\y = \frac{1}{2}x + \frac{1}{2}](https://tex.z-dn.net/?f=y%20-%200%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28x%20-%20%5B-1%5D%29%5C%5C%5C%5Cy%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28x%20%2B%201%29%5C%5C%5C%5Cy%20%3D%20%5Cfrac%7B1%7D%7B2%7Dx%20%2B%20%5Cfrac%7B1%7D%7B2%7D)
Answer:
8x10=80
4x8=32, 32 divided by 2 = 16
80+16= 96sq.ft
96 divided by 22 = 4.36
the answer is 5 whole quarts
24 × 9 (48Cans) = 9:48
12 × 10 (48Cans) = 10:48
12 × 9 (36Cans) = 9:36
