Question

Find the coordinates of the midpoint of a segment with the given endpoints W(-12, -7), T(-8, -4)

Answer 1

Finding the midpoint coordinates of any segment really boils down to finding the midpoints of each individual coordinate.

The x-coordinates of the two points are -12 and -8 - the number halfway between those two is -10, so that'll be the midpoint's x-coordinate. The y-coordinates are -7 and -4 - -5.5 is halfway between these two, so the y-coordinate will be 5.5.

Putting the two together, the midpoint of the segment WT has the coordinates (-10, -5.5).

Answer 2

You can find the midpoint with the following formula:

$\frac{x1+x2}{2}$, $\frac{y1+y2}{2}$

Substitute the corresponding values into the formula.

$\frac{(-12)+(-8)}{2}$, $\frac{(-7)+(-4)}{2}$

$\frac{-20}{2}$, $\frac{-11}{2}$

-10, -5.5

The coordinates of the midpoint are (-10, -5.5).
