Question

A line segment on a number line has it's endpoints at -9 and 6 . Find the coordinate of the midpoint of the segment. Selection is 1.5, -1.5, 2, or -3

Answer 1

-1.5

Explanation:

The middle of a line segment is its midpoint. To find the midpoint of a line segment, you just calculate the averages of the coordinates.

If a line segment on a number line has its endpoints at -9 and 6, then the coordinate of midpoint is

`(-9+6)/(2)=(-3)/(2)=-1.5`
