Answer:

y = 5

Explanation:

(-3, -4) and (-5, y)

slope formula:
(y_(2) - y_(1) )/(x_(2) - x_(1) )

Now plug in the numbers:
(y - (-4))/(-5 - (-3) )

Now set it equal to the slope:
(y - (-4))/(-5 - (-3) ) = -(9)/(2)

Simplify whatever you can:
(y +4)/(-2 ) = -(9)/(2)

Cross multiply:
2y + 8 = 18

Simplify:
2y = 10

Simplify again:
y = 5
