Question Answer
4 units to the right ( x+4, y )
8 units down ( x, y - 8 )
2 units left and 4 units up ( x - 2 , y + 4 )
reflect over the y axis ( - x, y )
reflect over the x axis ( x, - y )
reflect over the line y=x ( y, x )
rotate 90 degrees cc ( -y, x )
rotate 180 degrees cc ( -x, y )
rotate 270 degrees cc ( y, - x )
A ( -2, 5), B (2, 4), C (3, -3) Rotate AB 270 degrees cc A' (5,2) B' (4,-2)
A ( -2, 5), B (2, 4), C (3, -3) Rotate BC 90 degrees clockwise B' (4,-2) C' (-3,-3)
A ( -2, 5), B (2, 4), C (3, -3) Rotate ABC across the line y=x A' (5, -2) B' (4, 2) C' (-3,3)
A ( -2, 5), B (2, 4), C (3, -3) Translate AC 3 units left and 2 units down A' (-5, 3) C' (0, -5)
A ( -2, 5), B (2, 4), C (3, -3) Translate ABC 2 units right and 1 unit up, then dilate by a factor of 2 A' (0, 12) B' (8, 10) C' (10, -4)
A ( -2, 5), B (2, 4), C (3, -3) Dilate AC by a factor of 3 then rotate 90 degrees clockwise A' (15, 6) B' (-9, -9) (3y, -3x)
A ( -2, 5), B (2, 4), C (3, -3) Translate AB up 2 units and down 2 units, then dilate by factor of 2, then rotate 270 degrees clockwise. A' (-4, 10) B' (4, 8) A'' (-10,-4) B''(-8, 4)
Describe ( x-3, y+6 ) Translating 3 units left and 6 units up
If A' was rotated 270 degrees cc what were the original points of A? A (2, -5)
parent function of linear equation y = x
direct variation y = kx
E (-1, -3.5) F (4, -3) G (0, 1) H (-4, -2) Scale factor 0.5 Graph E (-1, -3.5) F (2, -1.5) G (0, 0.5) H (-2, -1)
