You did everything right. You leave "t" by itself because you don't have a given time frame. But I'll say you used the correct formula and showed your work well.

I hope this helps :)
Answer: (A), (B) and (E).
Step-by-step explanation: Given that ΔA’B’C’ with coordinates of A(-6,2),B’(-4,2), and C’(-6,-2) is the image of ΔABC after a translation of (x-3,y+2). We are to find the possible coordinates for the original vertices of ΔABC.
For vertex A, we have
So, the coordinates of vertex A are (-3, 0).
For vertex B, we have
So, the coordinates of vertex B are (-1, 0).
For vertex C, we have
So, the coordinates of vertex C are (-3, -4).
