No worries. Figured it out!
(wish I knew how to edit this into my original post, sorry mods!)
The question is:
Angle XYZ has vertices X(3, 1), Y(2, -4), and Z(-2, 0).
Use scalar multiplication to find the image of XYZ for a dilation with center (0, 0) and scale factor 2.5.
The problem being I have no idea how to do this. Any help?
