A polygon will be dilated on a coordinate grid to create a smaller polygon. Which rule could represent this dilation?
1) Multiply the x-coordinate and y-coordinate of each vertex by the same scale factor
2) Add the x-coordinate and y-coordinate of each vertex by the same scale factor
3) Subtract the x-coordinate and y-coordinate of each vertex by the same scale factor
4) Divide the x-coordinate and y-coordinate of each vertex by the same scale factor
