Dilations on the Coordinate Plane

To dilate a figure on the coordinate plane, multiply the x and y values of each ordered pair by the given _________ ___________.

• image

• point

• coordinate plane

When a dilation has occurred on the coordinate plane, you can find the

scale factor by choosing corresponding sides or vertices and setting up

a ratio of the _________ over the pre-image.

• original
