Answer:
x=5 x=-1 y=-5 y=4
Step-by-step explanation:
This might be difficult because I don't have a graph.
Plot the points on the graph (or on a separate piece of paper).
Find the lengths of the sides.
Multiply the sides by 3
Draw the graph again (perhaps on a separate piece of paper)
Shift the graph 2 places to the right and 1 place up.
Although I am not 100% certain (as I don't have paper with me) I believe the lines are at x=5 x=-1 y=-5 y=4
