Question

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

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 $x_1=8,y_1 = - 7,x_2=9,y_2 = 8$.

Step2: Calculate x - coordinate of mid - point

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

Step3: Calculate y - coordinate of mid - point

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

Answer:

$(8.5,0.5)$
