The answer is ( 7, -10) We need a right triangle width base 12 and height 5. By Pythagorean theorem, the hypotenuse is sqrt( 5^2 + 12^2) = sqrt( 25 + 144) = sqrt(169) = 13
Holly is at (2,2), so we start there. We move 5 squares to your RIGHT on your graph paper. That is (7,2)
From there we move 12 squares straight down. That is at (7,-10), which is where Joe is in the 4th quadrant.
