Question

what is the coordinate of the midpoint of $overline{tu}$? 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 $a=-2$ and $b = 1$.

Step2: Substitute values into formula

$M=\frac{-2 + 1}{2}$.

Step3: Calculate the result

$M=\frac{-1}{2}=-0.5$.

Answer:

$-0.5$
