Question

i dont know how to do the graph for x,y can you show me?

Answer 1

The midpoint of M of the line segment from A to B is

$\begin{gathered} M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}) \\ \text{Where} \\ A=(x_1,y_1) \\ B=(x_2,y_2) \end{gathered}$

So, in this case, you have

$\begin{gathered} A=(3,2) \\ B=(-7,8) \end{gathered}$$\begin{gathered} M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}) \\ M=(\frac{3+(-7)}{2},\frac{2+8}{2}) \\ M=(\frac{-4}{2},\frac{10}{2}) \\ M=(-2,5) \end{gathered}$

Graphing you have
