Given ABC with vertices A(-2,-2), B(1, -2). C(-1, 1). Dilate AABC by a scale factor of 5 and list the ordered pairs of AA'B'C'.
The rule of the dilation with center at origin is equal to
(x,y) -------> (ax,ay)
where
a is the scale factor
a=5
so
A(-2,-2)------------> A'(-10,-10)
B(1,-2) ------------> B'(5,-10)
C(-1,1) -----------> C'(-5,5)
