Hey, I asked this question before, but never received a response.
The line represented by 2y = 6x + 8 is dilated by a scale factor of k centered at the origin, such that the image of the line has an equation of y = 3x+ 12. What is the scale factor?

As I said before, the new line is twice as far away from (0,0), so the dilation must be 2
oops. Make that 3
