Question

find the location of b, the midpoint of $overline{ac}$.

Explanation:

Step1: Recall mid - point formula

The mid - point formula for two points $x_1$ and $x_2$ on a number line is $M=\frac{x_1 + x_2}{2}$. Here $x_1=-6$ (coordinate of $A$) and $x_2 = 8$ (coordinate of $C$).

Step2: Substitute values into formula

$B=\frac{-6 + 8}{2}$.

Step3: Calculate the result

$\frac{-6+8}{2}=\frac{2}{2}=1$.

Answer:

$1$
