Find the midpoint of the line segment with the given endpoints.<br> (-3,-7) and (3,0)
Crank
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) \\&#10;x_1=-3 \\ y_1=-7 \\ \\&#10;(3,0) \\&#10;x_2=3 \\ y_2=0 \\ \\&#10;\frac{x_1+x_2}{2}=\frac{-3+3}{2}=\frac{0}{2}=0 \\ \\&#10;\frac{y_1+y_2}{2}=\frac{-7+0}{2}=\frac{-7}{2}=-3.5 \\ \\&#10;\boxed{(0,-3.5)} - \hbox{the midpoint}
