The required dilation factor is 5
What is dilation?
Dilation is a way of increasing or decreasing the size of an object using a scale factor.
Given the given equation of a line -16x+8y=8 dilated by scale factor centered at the origin. If the image of the line after dilation is given by -16x +8y=40, the scale factor of dilation will be;
k = 40/8
k = 5
Hence the required dilation factor is 5
