Question

Use the midpoint formula to find the midpoint of the line segment whose endpoints are (-1,-3) and (3,-7). Please show all work.

Answer 1

If (a, b) and (c,d) are endpoints of a line then midpoint is given by the formula:

$\left (\frac{a+c}{2}, \frac{b+d}{2} \right )$

So, midpoint of endpoints (-1,-3) and (3,-7) is:

$\left (\frac{-1+3}{2}, \frac{-3+(-7)}{2} \right )$$= \left (\frac{2}{2}, \frac{-10}{2} \right )$

=(1.—5)
