Question

Find the second endpoint of the segment that has an endpoint at (9,5) and its midpointat (4, 2).

Answer 1

`\begin{gathered} \text{mid point = (}(x_1+x_2)/(2),(y_1+y_2)/(2)\text{)} \\ (4,2)=((9+x_2)/(2),(5+y_2)/(2)) \\ 4=(9+x_2)/(2) \\ 8=9+x_2 \\ x_2=8-9 \\ x_2=-1 \\ \\ 2=(5+y_2)/(2) \\ 4=5+y_2 \\ y_2=4-5 \\ y_2=-1 \end{gathered}`
