the midpoint of the line is (3,5)
one endpoint is (-1, -2)
now for another point,let the other point is (x, y)
so by midpoint formula,
[tex]3=\frac{-1+x}{2}[/tex][tex]\begin{gathered} 6=-1+x \\ x=6+1 \\ x=7 \end{gathered}[/tex]and
[tex]\begin{gathered} 5=\frac{-2+y}{2} \\ 10=-2+y \\ y=10+2 \\ y=12 \end{gathered}[/tex]thus, the other point is (7,12)
