Hi Aniyah
These problems are very quick when the center of dilation is (0,0). It's just two quick multiplication problems and you're done.
When a dilation with a scale k has center (0,0), then the image of (x,y) will be (kx, ky)
Your scale is 2 and your point is (1,-5), so your new coordinates will be 2×1 and 2×(-5)
A'=(2×1, 2×(-5))
A'(2,-10)
I'll bet you can figure out the other two on your own ;)
