Use scalar multiplication to determine the coordinates of the dilated figure. Then graph the pre-image and the image on the same coordinate grid. Quadrilateral STUV with vertex matrix |-9/6 6/1 9/-3 -4/-6| with scale factor 1/3

Polar coordinates is 8,9

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
