Answers:
x = 9
y = -3
==============================================================
How to get those answers:
Simply multiply the coordinates of the point (3,-1) by the scale factor 3.
The new x coordinate will be 3*3 = 9 and the new y coordinate will be -1*3 = -3.
The point (3, -1) moves to (9, -3) after applying the dilation.
The rule I used is [tex](x,y) \to (k*x, k*y)[/tex] where k is the scale factor, which is k = 3 in this case.
Note how k > 1 means the point moves further away from the origin. It also means we have an enlargement.
