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
[tex]\frac{-8+(-1)}{2}=\frac{-8-1}{2}=-\frac{9}{2}[/tex]
3) Hence, the midpoint of this line segment RP is -9/2 or -4.5
