Transformation reviwe/cheatsheet:
Translation: will put +/- after the x's and y's
(x,y)->(x+2,y-3)
Dilation: will put a number infront of x's and y's
(x,y)->(2x,.5y)
rotation: will just tell you to rotate.
"rotate ___° "
reflections: for x-axis and y-axis: will put a neg infront of x or y
(x,y)->(-x,y) x-axis
(x,y)->(x,-y) y-axis
for y-x, will just say "reflect over the line y=x"
Select ALL the transformations that will occur here:
(x,y) -> (x - 4, .5y)
Select ALL the transformations that will occur here:
(x,y) -> (-x+3, 2y)
Select ALL the transformations that will occur here:
(x,y) -> (x, 2y) rotated 90° clockwise
Reflect the x-axis then rotate 180°
(x,y) -> (-x, 2y)
(x,y) -> (x + 3, y+4) rotated 90° clockwise
rotated 180° clockwise then reflect y=x
(x,y) -> (x+5, 2y)
(x,y) -> (3x+4, y-2)
