How do I describe a transformation of a triangle that maps ABC onto A'B'C'. So if you can just explain the steps to me that would be great. Thanks

With no figures to consult, it's very hard to say ...
A is -3,4. B is -3,0. C is -1,3. Those are the ABC figures. For A'B'C' A' is -2,-3. B' is 2,-3. C'is -1,-1.
clearly AB has been rotated 1/4 turn to the left.
Since the triangle is still the same size (AB has the same length as A'B'), we just need to find the translation.
(-3,4) --> (-2,-3) so it has been moved by (1,-7)
Now just convert those two changes to your standard notation. Note that I have used point A as the center of the rotation. Using another point would have altered the translation.
