Question

question 4 of 13, step 2 of 2
consider the following pair of points.
(-3, -3) and (2, 9)
step 2 of 2: determine the midpoint of the line segment joining the pair of points.
answer

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 $x_1=-3,y_1 = - 3,x_2=2,y_2 = 9$.

Step2: Calculate x - coordinate of mid - point

$x=\frac{-3 + 2}{2}=\frac{-1}{2}=-\frac{1}{2}$

Step3: Calculate y - coordinate of mid - point

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

Answer:

$(-\frac{1}{2},3)$
