Question

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

Explanation:

Step1: Recall mid - point formula

For two points on a number line with coordinates $x_1$ and $x_2$, the mid - point formula is $\text{Mid - point}=\frac{x_1 + x_2}{2}$. Here, the coordinate of point $F$ is $-2$ and the coordinate of point $G$ is $-1$.

Step2: Substitute values into formula

Substitute $x_1=-2$ and $x_2 = - 1$ into the formula: $\frac{-2+( - 1)}{2}=\frac{-2 - 1}{2}=\frac{-3}{2}=-1.5$.

Answer:

$-1.5$
