Question

If (19,-12) is the midpoint of a segment and (7,11) is one of the endpoints, then what is the other endpoint?

Answer 1

the point is (19, -12)

and the mid point is (7, 11

now for other point calculation)

`\begin{gathered} 7=(19+x)/(2) \\ 14=19+x \\ x=14-19=-5 \end{gathered}`
`\begin{gathered} 11=(-12+y)/(2) \\ 22=-12+y \\ y=12+22=34 \end{gathered}`

so the other endpoint is (-5, 34).
