Question

find the midpoint of points a(8, -10) and b(-2, 0) graphically.
plot the line segment ab by clicking twice on the graph.

Explanation:

Step1: Recall mid - point formula

The mid - point formula for two points $(x_1,y_1)$ and $(x_2,y_2)$ is $M(\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})$. Here $x_1 = 8,y_1=-10,x_2=-2,y_2 = 0$.

Step2: Calculate x - coordinate of mid - point

$x=\frac{8+( - 2)}{2}=\frac{8 - 2}{2}=\frac{6}{2}=3$.

Step3: Calculate y - coordinate of mid - point

$y=\frac{-10 + 0}{2}=\frac{-10}{2}=-5$.

Answer:

$(3,-5)$
