Question

GEOMETRY IAWhat is the coordinate of the midpoint of RP?

Answer 1

1) Examining the number line, we know that RP is a line segment. And the midpoint is located at half the segment RP.

2) Then on the number line we can write out, the following:

We can take the average of those points -8 and -1

$\frac{-8+(-1)}{2}=\frac{-8-1}{2}=-\frac{9}{2}$

3) Hence, the midpoint of this line segment RP is -9/2 or -4.5
