Answer:

Point P = (-9,11)

Step-by-step explanation:

Point M: (1,3)               X and Y have the 2 on the bottom right of them

Midpoint N: (-5,7)

Point P: (X*2, Y*2)

( 1 + X*2          3  + Y*2 )

( _______     ________ )     =     (-5 , 7)

(      2         ,          2          )

( 1 + X*2 )

( _____ )     = -5  

(      2     )

Then multiply the left equation above by 2, and that cancels out the 2 being

divided on the bottom. Also, multiply the -5 by 2 and you get -10

1 + X*2 = -10

+1             +1

__________

X*2 =       -9    

X = -9

( 3 + Y*2 )

( ______ )       =  7

(      2       )

Then multiply the left  equation above by 2, and that cancels out the 2 being divided on the bottom. Also, multiply the 7 by 2 and you get 14

3 + Y*2 = 14

-3             -3

_________

Y*2 =       11

Y = 11

Hope this helps, good luck! :)
