Question

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

Explanation:

Step1: Recall mid - point formula

For two points $a$ and $b$ on a number line, the mid - point $M=\frac{a + b}{2}$. Here $a=-63$ and $b = - 62$.

Step2: Calculate the mid - point

$M=\frac{-63+( - 62)}{2}=\frac{-63 - 62}{2}=\frac{-125}{2}=-62.5$

Answer:

$-62.5$
