Graph the triangle with vertices X(−3, 2), Y(2, 3), and Z(1,−1) and its image after a dilation with scale factor k=−3.

What are the following coordinates for the dilation?

Please show all work on how you got your answer.

Dilation involves changing the size of a shape.

See attachment for the graphs of the image and the pre-image

The coordinates of the triangle is given as:

The scale factor (k) is given as:

So, the coordinates of the image are:

So, the coordinates of the image are:

See attachment for the graphs of the image and the pre-image

X(−3, 2), Y(2, 3), Z(1,−1)

Good job on graphing XYZ.  Dilation by k=-3 just means we multiply all the coordinates by -3:

X'(9,-6), Y'(-6,-9), Z(-3,3)

Since you know how to plot coordinates I'll leave that to you.
