Question

what is the coordinate of the midpoint of $overline{lm}$? 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, mid - point $=\frac{a + b}{2}$. Here $a=-4$ and $b = - 3$.

Step2: Calculate mid - point

$\frac{-4+( - 3)}{2}=\frac{-4 - 3}{2}=\frac{-7}{2}=-3.5$

Answer:

$-3.5$
