Question

find the midpoint of points a(3, 9) and b(-7, 3) graphically. plot the line segment ab by clicking twice on the graph. start over answer attempt 1 out of 2 you must answer all questions above in order to submit.

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 $x_1=3,y_1 = 9,x_2=-7,y_2 = 3$.

Step2: Calculate x - coordinate of mid - point

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

Step3: Calculate y - coordinate of mid - point

$y=\frac{9 + 3}{2}=\frac{12}{2}=6$.

Answer:

$(-2,6)$
