Question

can you please help me with number 4 please, I understand for the most part but need to make sure the answer is right

Answer 1

4) D:(x, y) - - (3x, 3y) means that we would dilate by a fator of 3. To do this, we would multiply the coordinate of each vertices by 3.

From the information given, the vertices are

A(0, 0)

B(1, 2)

C(3, - 2)

After dilation, the new vartices are

A(0 *3, (0 * 3) = (0, 0)

B(1 * 3, 2 * 3) = (3, 6)

C(3 * 3, - 2* 3) = (8, - 6)
