Answer:
y=-5x-3
Step-by-step explanation:
You need to plug both of them into the equation
y=mx+b
This would give us
7=m(-2)+b
-8=m+b
15=-3m
m=-5
y=-5x-3
Answer:
y=-5x-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-8-7)/(1-(-2))
m=-15/(1+2)
m=-15/3
m=-5
y-y1=m(x-x1)
y-7=-5(x-(-2))
y-7=-5(x+2)
y=-5x-10+7
y=-5x-3
