Point B has coordinate B(1, -1).

What is the coordinate of B' under a scale factor of 3?

(1,-1)

(3, 3)

(-2,2)

4-6, 6)

B' is  (3, -3)

Step-by-step explanation:

When we have a point with coordinate (x, y) and we do a dilation (around the center) with a scale factor of A, the coordinate of the new point will be:

A*(x,y) =(A*x, A*y)

Here our point is (1, -1) and the factor is 3, so the new point will be:

(3*1, 3*-1) = (3, -3)

first one is a: renaming a fraction. second one is c: de-c
