what are the coordinates after a reflection across the origin from (1,1)
(-1,-1)
100

What are the two directions we can rotate on the coordinate grid?

clockwise and counterclockwise

100
what is a translation ?
the moving of a point on a coordinate plane
100
what is a dilation ?
a dilation is the growing or shrinking of a shape
100

solve. x + 10 = -2

-12

200
What is the definition of a reflection?
a reflection is when a point is mirrored over a line or point on the coordinate plane
200
if (x,y) is rotated 90 degrees what is the outcome?
(-y,x)
200

whAT IS THE RULE FOR (1,1) TO (2,2)

(X+1,Y+1)

200
what is the thing used to determine the size of the image?
a scale factor
200

Distribute.  3(x + 5) 

3x + 15

300
What is the final coordinates after (x,y) is reflected over the y axis?
(-x,y)
300
WHAT IS THE RULE FOR ROTATING 180 DEGREEES?
(-x,-y)
300
is the rule for a translation always the same?
no
300
if i used a scale factor of 2 how much bigger would the shape get?
twice the size
300

Combine like terms. 2x +10 + 3x -2 

5x + 8

400
what is the rule for a reflection across the x axis?
(x,y) to (x,-y)
400
what is a rotation?
a "spin" of a point or shape around a point
400

starting at the origin if you add 5 to x and add 12 to y what are your new points

(5,12)

400
if i used a scale factor of 1 would the shape get bigger or smaller?
it would stay the same size
400

Solve. 2y = 10   y=?

y = 5

500

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

500

if you rotated (x,y) 360 degrees what would you get?

(x,y)

500

starting at the origin what is (x-9,y-3)

(-9,-3)

500

Would a scale factor of .5 make the shape bigger or smaller

smaller

500
Solve. 2(x+6) = 10      x=?

x = -1
