Answers:
A' (12, 3)
B' (10, -5)
C' (7, 0)
==========================================================
Step-by-step explanation:
The rule of x turning into x+18 means we add 18 to the x coordinate of the given point. Point A has x = -6, so it leads to x+18 = -6+18 = 12 being the x coordinate of the image point A'. The y coordinate is y-12 = 15-12 = 3
A(-6,15) translates or shifts to A ' (12, 3)
We have shifted 18 units to the right and 12 units down.
Apply this same logic to the point B(-8,7) and you should get to B ' (10, -5)
Similarly, the preimage point C(-11,12) moves to C ' (7, 0)
The diagram is shown below.
