1) (-7,2)
y=2, -x+4=11, -x=11-4=7, x=-7
2) (-3,4)
-x+2y=11
y=4, -x+8=11, -x=3, x=-3
3) (1,6)
-x+2y=11
y=6, -x+12=11,-x=-1, x=1
Answer: (-3,5) would be the orgin but if you rotated it more it would be (3,-5)
Step-by-step explanation: you can use a peace of gragh paper to do that it makes it a lot easer.
-8+y=-3y-2
-8+2=3y-y
-6=2y
y=-3
