Question

find the midpoint of points a(-7, -8) and b(3, 2) graphically. you may press submit or click the graph again to replot the midpoint.

Explanation:

Step1: Use 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 $x_1=-7,y_1 = - 8,x_2=3,y_2 = 2$.

Step2: Calculate x - coordinate of mid - point

$x=\frac{-7 + 3}{2}=\frac{-4}{2}=-2$.

Step3: Calculate y - coordinate of mid - point

$y=\frac{-8 + 2}{2}=\frac{-6}{2}=-3$.

Answer:

$(-2,-3)$
