Translation: (x, y)➡️(x+3, y-1)

You have to get the original coordinates of a point and plug it in to the x and y variable then solve it and it should give you new points and then just put the new points in the coordinate plane and there’s your translation (sorry i didn’t solve it but i hope it helps)

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
