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 numbers \(a\) and \(b\) on a number line, the mid - point \(M=\frac{a + b}{2}\). Here \(a=-55\) and \(b = - 50\).

Step2: Substitute values

\(M=\frac{-55+( - 50)}{2}=\frac{-55 - 50}{2}=\frac{-105}{2}=-52.5\)

Answer:

\(-52.5\)
