Answer: y = 3/2x + 1
Step-by-step explanation: For a perpendicular line, take the reciprocal of "m" and reverse the sign.
- 2/3 becomes +3/2
Then substitute the y and x values of the given coordinate into the equation and solve for "b"
y = mx + b
-2 = 3/2(-2) + b
-2 = -3 + b
-2 +3 = b
+1 = b Substitute for b in y = (3/2)x + 1

Step-by-step explanation:
The question has missing details. So, I'll solve using a general assumption.
Let one of the coordinates of the figure be
Let the scale factor be n
When dilated, the new figure is:
To return the image back to the original figure, the new scale factor mus be a reciprocal of the previous scale factor i.e.
So:
Substitute n(x,y) for A';
Take for instance:
-- scale factor
To get A from A', using the analysis above
