please answer!! i need help .. ur a life saver if u do :)) oh and pls only answer if u know how to do this!

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 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.

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

factorizing, we get that:
