Answer:
y = -2x + 16
Explanation:
the way to solve this is to use the formula to find the slope
m = (y2 - y1) / (x2 - x1)
(-2,20) (5,6)
(20-6) / (-2 - 5)
14/ -7
-2 = m
then you can substitute m and one of the given points into the y = mx + b to find b
y = mx + b
20 = (-2)-2 + b
20 = 4 + b
16 = b
putting it all together, you get y = -2x + 16
