Question

find the location of b, the midpoint of ac. location of b:

Explanation:

Step1: Identify coordinates of A and C

From the number - line, \(A=- 1\) and \(C = 2\).

Step2: Apply 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 \(x_1=-1\) and \(x_2 = 2\), so \(B=\frac{-1 + 2}{2}\).

Step3: Calculate the value

\(\frac{-1+2}{2}=\frac{1}{2}=0.5\)

Answer:

\(0.5\)
