Question

Point L is located at (4, -3) and M is located at (-8, 5). Find the y value of the point that lies halfway between L and M.

Answer 1

y = 1

Explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[
`(1)/(2)` (x₁ + x₂ ),
`(1)/(2)` (y₁ + y₂ ) ]

Here (x₁, y₁ ) = (4, - 3) and (x₂, y₂ ) = (- 8, 5), thus the y value of midpoint is

y =
`(1)/(2)` (- 3 + 5) = 0.5 × 2 = 1
