Tbh I never did this type of problem before but from what I've tried to google shouldn't you translate each vertices right 3 and up 1. I have no clue here but maybe I should stick around to learn

ok... so start with the point (1, 4) 

3 left means that x = 1 - 3 = -2

and up 1 means y = 4 + 1 = 5

so (1, 4) transforms to (-2, 5)

apply this rule to the other points. 

x: subtract 3

y add 1

hope it helps
