Question

What are the coordinates of ABC after a dilation with center (0,0) and a scale factor of 3?​

Answer 1

By the scle factor of 2 and a then inceroet

Answer 2

Note that both the x and y coordinates are multiplied by the SAME value, k. Given ΔDEF with center of dilation the origin (0,0) and scale factor of 2, plot ΔD'E'F'. As shown in the formula above, multiply each x and y coordinate value by the scale factor of 2 to find the new coordinator
