Question

Find the midpoint of the line segment with the given endpoints.
(-3,-7) and (3,0)

Answer 1

The coordinates of the midpoint:
$(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$
x₁,y₁ - the coordinates of one endpoint
x₂,y₂ - the coordinates of the other endpoint

$(-3,-7) \\ x_1=-3 \\ y_1=-7 \\ \\ (3,0) \\ x_2=3 \\ y_2=0 \\ \\ \frac{x_1+x_2}{2}=\frac{-3+3}{2}=\frac{0}{2}=0 \\ \\ \frac{y_1+y_2}{2}=\frac{-7+0}{2}=\frac{-7}{2}=-3.5 \\ \\ \boxed{(0,-3.5)} - \hbox{the midpoint}$

Answer 2

(0,3.5)
