1. Review
(3,3) (4,-2) (6,5) (9,1)

2. Review 3, 6, 9, 12: Find the 20th term

3. Function/slope-intercept form

4. Information Equation in 2 variables: equation with 2 variables.
Ex: 2x – y = 6
Solution: ordered pair makes equation true.
Ex: (2, 3) is a solution to 2x – 3y = -5

5. Check for solutions Tell if pair is a solution to 3x + 2y = -8
(4, -12)
Tell if pair is a solution to 3x + 2y = -8
(10, -19)

6. Check for solutions Tell if pairs are solutions to 2x – y = 5 (1, -3)
(4, 7 )
Tell if pairs are solutions to 3x + 2y = -8
(0, 4)
(-2, -1)

7. Information Slope intercept form: y = mx + b M = slope B = y-intercept
Identify the slope and y-intercept
Y = -2/3x + 3
Y = 2x – 4
Y = 4x + 3

8. Function/slope-intercept form
Function form: solve for y.
Ex: 3x + y = 7
2x – 3y = 3
3x – 2y = 6

9. Function/slope-int Form
Y – x = 1
3x – 5y = -1
2x + 3y = 12

10. Change to slope intercept form
3x – 2y = 12
-2x + 4y = 16

11. Change to slope intercept form
X + y = 3
-2x – 3y = 24
5x – 7y = 28
5x + y = 3
