I am asked to graph a triangle with the vertices (-3, 2), (5, 6), and (6, -4) after performing a dilation about the origin of scale factor 4.
What does "about the origin" mean? Is this the same as just multiplying the ordered pairs by 4? Are the new vertices (-12, 8), (20, 24), and (24, -16)?

you are correct.
A dilation might be around some other point, in which case distances to that point are scaled, and things get much more complicated.
