Answer 1

y = - 41

Explanation:

The midpoint of the line is

`(y+31)/(2)` = - 5 ( multiply both sides by 2 )

y + 31 = - 10 ( subtract 31 from both sides )

y = - 41

Answer 2

The midpoint is -41

Explanation:

(y+31)÷2=-5, then multiply by 2 on both sides to cancel out the ÷2. y+31=-10.

Then subtract 31 on both sides to cancel out the +31 and leave the variable alone on one side. Then you get y=-41.
