Question

What is the image of (-9,6) after a dilation by a scale factor of 4 centered at theorigin?

Answer 1

The formula for dilation is:

D(x,y) = (k*x, k*y)

which means that you need to multiply each coordinate by the factor of the dilation (k) which in our case is "4".

Therefore the image of the point (-9,6) after dilation is: (-36, 24)
