Answer:

(8,-3)

Step-by-step explanation:

mid point formula for graph:

[tex](\frac{x_{1}+ x_{2} }{2} ,\frac{y_{1} +y_{2} }{2} )[/tex]

[tex](\frac{6+x}{2} ,\frac{-7\\+y}{2} )[/tex]

[tex]\frac{6+x}{2} =7[/tex]

[tex]x[/tex] is the x cordinate of B which will be

8

TO FIND Y:

[tex]\frac{-7\\+y}{2} =-5[/tex]

[tex]y=-3\\[/tex]
