Slope and solving

Slope = rise / run

Remember to start at one point and work your way towards the other point  to make sure your signs are right.

After break we started looking at solving.  We needed a bit of a refresher from grade 8, so did some questions from the board solving equations with one variable.

HOMEWORK:

Slope workbooklet - all five pages

Questions from the board:

1. x + 7 = 15
2. 2x + 3 = 15
3. 3x - 7 = 14
4. 2 + 3x = 17
5. 5x + 14 = -1
6. 16x-6x + 10 = 0
7. 4x = 8
8. -2x + 7 = -3
9. -4x + 12 = 0
10. -4x + 3 = 3x - 11
11. -7x - 3 = 2x - 4
12. -5x + 3x - 1 = 2x + 10x
13. -3x + 2 = 4x + 1
14. 121x + 13 = 115x +14
15. x/2 + 3 = 5
