Question

Find the midpoint of the line segment with end coordinates of:

(-2,-4) and (-1,-5)
Give coordinates as decimals where appropriate.

Answer 1

The midpoint of this line segment is (-1.5, -4.5).

Explanation:

In finding the midpoint of a line segment we are actually averaging the x- and y-coordinates of the endpoints:

-2 -1

x-coordinate of midpoint = --------- = -3/2 = -1.5

2

-4 -5

y-coordinate of midpoint = ---------- = -4.5

2

The midpoint of this line segment is (-1.5, -4.5).
