Question

consider the following pair of points.
(8, -7) and (9, 8)
step 2 of 2: determine the midpoint of the line segment joining the pair of points.

Explanation:

Step1: Recall mid - point formula

The mid - point formula for two points $(x_1,y_1)$ and $(x_2,y_2)$ is $(\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})$. Here $x_1 = 8$, $y_1=-7$, $x_2 = 9$, and $y_2 = 8$.

Step2: Calculate the x - coordinate of the mid - point

$x=\frac{8 + 9}{2}=\frac{17}{2}=8.5$

Step3: Calculate the y - coordinate of the mid - point

$y=\frac{-7 + 8}{2}=\frac{1}{2}=0.5$

Answer:

$(8.5,0.5)$
