Draw the image of the figure with the given vertices under a dilation with the given scale factor centered at the origin j(-2,2)
Elenna [48]

Answer:

See Attachment.

Step-by-step explanation:

To create the new figure, we must multiply each coordinate by the scale factor, which is 1/2 in this case.

So j(-2,2) becomes j'(-1,1)

K(4,2) becomes K'(2,1)

L(4,-2) becomes L'(2,-1)

and M (-2,-2) becomes M'(-1,-1)

The scale factor is between 1 and 0 which means that this dilation is a reduction that will shrink the original figure to a smaller one.
