Question

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

Explanation:

Step1: Recall mid - point formula

For two points \(a\) and \(b\) on a number line, the mid - point \(M\) is given by \(M=\frac{a + b}{2}\). Here \(a = 3\) (coordinate of \(M\)) and \(b = 5\) (coordinate of \(N\)).

Step2: Calculate mid - point

Substitute \(a = 3\) and \(b = 5\) into the formula: \(\frac{3+5}{2}=\frac{8}{2}=4\).
