Answer:
A'(-1, -1)
Step-by-step explanation:
Dilation about the origin multiplies each individual coordinate value by the dilation factor.
A' = (1/3)A = (1/3)(-3, -3) = (-1, -1)
(-1, -1)
When you figure scale factor, it's always a number that's multiplied into the coordinates of the pre-image. The coordinates of A are (-3, -3), so multiplying in the scale factor of 1/3 divides each of those coordinates by 3. -3/3 = -1
42sq
5:7
30 sq: x sq
30/5=6 sq for 1 of the ratio
6*7=42 sq for 7 of the ratio
