reflection
What are the two directions we can rotate on the coordinate grid?
clockwise and counterclockwise
solve. x + 10 = -2
-12
whAT IS THE RULE FOR (1,1) TO (2,2)
(X+1,Y+1)
Distribute. 3(x + 5)
3x + 15
Combine like terms. 2x +10 + 3x -2
5x + 8
starting at the origin if you add 5 to x and add 12 to y what are your new points
(5,12)
Solve. 2y = 10 y=?
y = 5
If your pre-image point is (2,2) and your image(after) point is (-2,2), which axis did the point reflect over?
The y-axis
if you rotated (x,y) 360 degrees what would you get?
(x,y)
starting at the origin what is (x-9,y-3)
(-9,-3)
Would a scale factor of .5 make the shape bigger or smaller
smaller
x = -1
