Aline segment has endpoints at (-4,13) and (18,-3.5).

what is the y-coordinate of the midpoint of the line segment?

4.75

Explanation:

Make a right triangle

It goes right 22 and down 16.5

Those are the two sides

22^2+16.5^2=h^2

484+272.25=h^2

h=27.5

If it were half, it would go right 11, down 8.25

With hypotenuse being=13.75

Being at (7,4.75)

Hope you get it!
