Question

find the location of n, the midpoint of mp.

Explanation:

Step1: Identify the coordinates of M and P

The coordinate of M is 6 and the coordinate of P is 12.

Step2: Apply mid - point formula

The mid - point formula for a one - dimensional number line is $N=\frac{M + P}{2}$. Substitute M = 6 and P = 12 into the formula: $N=\frac{6+12}{2}$.

Step3: Calculate the value of N

First, add 6 and 12: $6 + 12=18$. Then divide by 2: $\frac{18}{2}=9$.

Answer:

9
