Question

what is the coordinate of the mid - point of $overline{kl}$? k l -40 -35 -30 -25 -20 write your answer as an integer, a decimal, or mixed number in simplest form.

Explanation:

Step1: Recall mid - point formula

For two points \(x_1\) and \(x_2\) on a number line, the mid - point \(M=\frac{x_1 + x_2}{2}\). Here \(x_1=-40\) and \(x_2=-35\).

Step2: Calculate the mid - point

\(M=\frac{-40+( - 35)}{2}=\frac{-40 - 35}{2}=\frac{-75}{2}=-37.5\)

Answer:

\(-37.5\)
