Question

what is the midpoint of ab? -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 a f g h i b point f point g point h point i

Explanation:

Step1: Identify coordinates of A and B

The coordinate of A is -6 and of B is 8.

Step2: Use 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 $x_1=-6$ and $x_2 = 8$, so $\frac{-6 + 8}{2}=\frac{2}{2}=1$.

Step3: Find the corresponding point

The point with coordinate 1 on the number line is point G.

Answer:

point G
