Answer:
y = -2x+1
Step-by-step explanation:
The slope is found by
m = (y2-y1)/(x2-x1)
= (-1-5)/(1--2)
= -6/(1+2)
= -6/3
= -2
Then we can use point slope form to make an equation
y-y1 = m(x-x1)
y-5 = -2(x--2)
y-5 = -2(x+2)
Distribute
y-5 = -2x -4
Add 5 to each side
y-5+5 = -2x-4+5
y = -2x+1
This is in point slope form
