Question

Can you help me with this assignment

Answer 1

the formula of the midpoint is

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

A are (-3,4) --> (x1,y1)

B are (x2,y2)

we can repalce A and the midpoint and the formula

`((-3+x2)/(2),(4+y2)/(2))=(-5,2)`

and we can equal each coordinate to find x2 and y2

first x2

`\begin{gathered} (-3+x2)/(2)=-5 \\ \\ -3+x2=-5*2 \\ x2=-10+3 \\ x2=13 \end{gathered}`

now y2

`\begin{gathered} (4+y2)/(2)=2 \\ \\ 4+y2=2*2 \\ y2=4-4 \\ y2=0 \end{gathered}`

so B is

`(13,0)`
