2. What is the effect of the following rule on the original (x, y)? (3x + 4, 5y – 2) The width gets 3 times bigger, the height gets 5 times bigger, and the figure translates right 4 units and down 2 units.

3. What is the effect of the following rule on the original (x, y)? (4x + 1, 4y + 3) The width and height get 4 times bigger, and the figure translates right 1 unit and up 3 units.

4. What is the effect of the following rule on the original (x, y)? (x - 5, y + 3) The width and height stay the same and the figure translates left 5 units and up 3 units.

5. What is the effect of the following rule on the original (x, y)? (.5x, .5y) The width and height get .5 times smaller.

6. 14x + 2 + 80 = 180 X = 7

7. X + 67 = 60 X = -7

8. 6x + 14 = 80 X = 11

9. 6x + 8 + 130 = 180 X = 7
