Question

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

Explanation:

Step1: Recall mid - point formula on a number line

The mid - point of two numbers \(a\) and \(b\) on a number line is given by \(\frac{a + b}{2}\). Here \(a = 5\) (coordinate of \(J\)) and \(b=7\) (coordinate of \(K\)).

Step2: Calculate the mid - point

Substitute \(a = 5\) and \(b = 7\) into the formula: \(\frac{5+7}{2}=\frac{12}{2}=6\).

Answer:
