Mathematics
1 answer:
frozen [14]3 years ago
7 0

Answer:

y = -5

Step-by-step explanation:

Given two points, we know the slope is

m = (y2-y1)/(x2-x1)

-4 = (-1-y)/(-5--4)

-4 = (-1-y) /(-5+4)

-4 =/(-1-y)/-1

Multiply each side by -1

-1*-4 = (-1-y) /-1*-1

4 = -1-y

Add 1 to each side

4+1 = -1+1-y

5 = -y

Multiply each side by -1

-1*5 = -y*-1

-5 = y
