Answer: x = 33, y = 95
Step-by-step explanation:
The defintion of a parallelogram states that opposite sides are equal.
Therefore, 3x - 4 = 65 and y - 4 = 91.
We can now solve these equations.
3x = 69
x = 33
--------------------
y = 95
To find the pre image you need to back track on the image. To get to the image you used (x-6,y+8). Now you need to use the exact opposite to get back to the pre image. For this you would change the signs to look like (x+6,y-8). Now we just apply this to (-4,1).
(-4+6,1-8)
(2,-7) should be the pre image point.
