what is the value of y (-4,-3)(-8,y) slope is -7/4

Question

I need help finding the value of y

Answer 1

the underlying equation that you're trying to solve here is

-7/4 = (y + 3) / (-8 + 4)

solving that algebraically for the value of "y" yields

-7/4 = (y + 3) / -4

7 = y + 3

y = 4

Answer 2

-7/4 = [y - (-3)]/[-8 - (-4)]

 

-7/4 = (y + 3)/(-4)

 

7 = y + 3

 

y = 4
