Question

Triangle ABC has coordinates A(2,6), B(-4,5), C(-4,2). Graph triangle ABC and A'B'C' for the dilation (x,y) (-2x, -2y).

Answer 1

First graph points $A(2,6),B(-4,5)$ and $C(-4,2)$ then using the dilation information calculate points $A'(-4,-12), B'(8,-10)$ and $C'(8,-4)$ and plot them.

Hope this helps.
