Okay so to translate a shape, do as the instructions say for each point.
A. (3,-4)
First move the point 5 units to the left, the x should be: -5
Now move the 6 units point up, the y should be: 2
B. (9,0)
You do the same thing and the x should be: 4 while the y should be: 6
C. (7,-6)
Repeat the same step from point A to get (2,0)
For easier way to do this, remember that left and right correspond to the x. So left = subtracting and right = adding, so you would just subtract 5 from the x. Next, up and down correspond to the y, therefore up = adding and down = subtracting.
Hope this helps c:
