Question

find the midpoint of points a(-10, -1) and b(-7, -6) graphically. you may press submit or click the graph again to replot the midpoint. answer attempt 2 out of 2

Explanation:

Step1: Recall mid - point formula

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

Step2: Identify coordinates

Here, $x_1=-10,y_1 = - 1,x_2=-7,y_2=-6$.

Step3: Calculate x - coordinate of mid - point

$x=\frac{-10+( - 7)}{2}=\frac{-10 - 7}{2}=\frac{-17}{2}=-8.5$.

Step4: Calculate y - coordinate of mid - point

$y=\frac{-1+( - 6)}{2}=\frac{-1 - 6}{2}=\frac{-7}{2}=-3.5$.

Answer:

$(-8.5,-3.5)$
