Answer:
y = 9x - 43
Step-by-step explanation:
First, find the slope using m = y2-y1/x2-x1.
m = -7 - 2/ 4-5
m= -9/-1
(negative multiplied by negative is positive)
m = 9
Plug in the slope into y = mx+b
^Using (5,2), substitute the x and y values, and use 9 for m.
2 = 9(5) + b
2 = 45 +b
(Subtract 45 from both sides)
-43 = b
The final answer is :
y = 9x + -43
y = 9x - 43
