Question

Find the coordinates of the midpoint of the line joining the points and show your work.

Answer 1

formula of midpoint

`((x1+x2)/(2),(y1+y2)/(2))`

the we replace (7,1) and (-1,3)

`((7+(-1))/(2),(1+3)/(2))`

simplify to solve

`\begin{gathered} ((7+1)/(2),(4)/(2)) \\ \\ ((8)/(2),(4)/(2)) \\ \\ (4,2) \end{gathered}`

Midpoint is (4,2)
