Question

ch1 test b (oct25) (resumed) plane geometry 20 (athus rocha, id: 13886586) find the midpoint of a(2,-1) and b(-6,0). (3 pts) midpoint ( )

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 $x_1 = 2,y_1=-1,x_2=-6,y_2 = 0$.

Step2: Calculate the x - coordinate of the mid - point

$x=\frac{2+( - 6)}{2}=\frac{2 - 6}{2}=\frac{-4}{2}=-2$.

Step3: Calculate the y - coordinate of the mid - point

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

Answer:

$(-2,-\frac{1}{2})$
