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 - 1 and the coordinate of F is 3.

Step2: Use the mid - point formula for a number line

The mid - point formula for two points \(a\) and \(b\) on a number line is \(\frac{a + b}{2}\). Here \(a=-1\) and \(b = 3\), so the mid - point is \(\frac{-1+3}{2}\).

Step3: Calculate the mid - point

\(\frac{-1 + 3}{2}=\frac{2}{2}=1\)
