Question

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

Explanation:

Step1: Identify coordinates

$A=-3$, $C = 7$

Step2: Apply mid - point formula

The mid - point formula for two points $x_1$ and $x_2$ on a number line is $\frac{x_1 + x_2}{2}$. Here $x_1=-3$ and $x_2 = 7$, so $B=\frac{-3 + 7}{2}$

Step3: Calculate the value

$\frac{-3+7}{2}=\frac{4}{2}=2$

Answer:

$2$
