Answer:
Triangle ABC has been translated 3 units to the right and 5 units down.Step-by-step explanation:
This is the concept of translation;
Given that triangle A (-1,3), B(-1,1), C(3,1) has been translated to A'(2,-1), B'(2,-4), C(6,-4)
the from the diagram we see that the coordinates of the triangle ABC have been moved by 3 units to the right while the y coordinates have been moved by 5 units down to form A',B',C'.
We therefore conclude that the correct statement is:
Triangle ABC has been translated 3 units to the right and 5 units down.
