Question

what is the coordinate of the midpoint of ef? write your answer as an integer or a decimal, or mixed number in simplest form.

Explanation:

Step1: Identify the coordinates of E and F

The coordinate of E is - 20 and the coordinate of F is 20.

Step2: Use the mid - point formula

The mid - point formula for two points \(x_1\) and \(x_2\) on a number line is \(\frac{x_1 + x_2}{2}\). Here \(x_1=-20\) and \(x_2 = 20\), so \(\frac{-20 + 20}{2}\).

Step3: Calculate the result

\(\frac{-20+20}{2}=\frac{0}{2}=0\)

Answer:
