Assume a graphics object has vertices at the points (1,2),(2,6),(6,7) and (3,9)

How would i scale the original graphics object by a scaling factor of 3 about its center and calculate where the point (1,2) ends up?

To scale the original graphics objects given the scaling factor, you need to multiply the coordinates of each given point using the scaling factor. Therefore, the point that has coordinates (1,2) is calculated by multiplying 1 * 3 = 3 and 2 * 3 = 6 to get the new points as (3,6).
