Question

what is the coordinate of the midpoint of $overline{bc}$?
write your answer as an integer or a decimal, or mixed number in simplest form.

Explanation:

Step1: Recall mid - point formula

For two points $x_1$ and $x_2$ on a number line, the mid - point $M=\frac{x_1 + x_2}{2}$. Here $x_1=-5$ and $x_2 = 10$.

Step2: Calculate the mid - point

$M=\frac{-5 + 10}{2}=\frac{5}{2}=2.5$

Answer:

$2.5$
