Question

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

Explanation:

Step1: Recall mid - point formula

For a one - dimensional line segment with endpoints $x_1$ and $x_2$, the mid - point $M=\frac{x_1 + x_2}{2}$. Here, $x_1 = 1$ (coordinate of $G$) and $x_2=2$ (coordinate of $H$).

Step2: Calculate the mid - point

$M=\frac{1 + 2}{2}=\frac{3}{2}=1.5$

Answer:

$1.5$
