Question

find the midpoint of di. d = (-7,0) i = (6,-2) mp =

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, for points $D(-7,0)$ and $I(9,-2)$, $x_1=-7$, $y_1 = 0$, $x_2=9$, $y_2=-2$.

Step2: Calculate x - coordinate of mid - point

$x=\frac{-7 + 9}{2}=\frac{2}{2}=1$

Step3: Calculate y - coordinate of mid - point

$y=\frac{0+( - 2)}{2}=\frac{-2}{2}=-1$

Answer:

$(1,-1)$
