Solution

Step 1:Find the coordinates of image after dilation.

Given, coordinates and scale factor is B(3,3),C(3,6),D(6,6),E(6,3);k=13.

Using the above criteria of dilation.

B(3,3)=B'(3×13,3×13)=B'(1,1)C(3,6)=C'(3×13,6×13)=C'(1,2)D(6,6)=D'(6×13,6×13)=D'(2,2)E(6,3)=E'(6×13,3×13)=E'(2,1)

Step 2: Plot the graph.

Step 3: Final answer.

Hence, the coordinates of image after dilation is B'(1,1),C'(1,2),D'(2,2),E'(2,1).
