4 How to tell if a slope is positive

5 The Slope Formula

6 The Slope Intercept Formula Y = MX + b  M is the slope of the equation.  M is the value attached to the x  B is the y intercept.  B is always the value of the equation when x = o.

7 The Slope Formula

9 10/29 Warm up  1. What is the slope of the following two points? (3, 11) (6, 17)  2. What is the slope of the following two points? (-3, 7) (6, -6)

10 John makes $15 an hour. He plans on working 10 hours this weekend. Write a function that shows this.  A. What is the function equation of this problem?  B. How much would he make if he worked 0, 3, 5, 8 or 10 hours?

11 John makes $15 an hour. He plans on working 10 hours this weekend. Write a function that shows this.  A. What is the function equation of this problem?  f(x) = 15x

12 John makes $15 an hour. He plans on working 10 hours this weekend. Write a function that shows this.  B. How much would he make if he worked 0, 3, 5, 8 or 10 hours?  f(x) = 15x F(x) = 15xF(x) = ?( ) F(0) = 15(0)F(0) = 0(0, 0) F(3) = 15(3)F(3) = 45(3, 45) F(5) = 15(5)F(5) = 75(5, 75) F(8) = 15(8)F(8) = 120(8, 120) F(10) = 15(10)F(10) = 150(10, 150)

13 Joan gets paid $35 a day to watch kids and $5 per kid. Write a function that shows this.  A. What is the function equation of this problem?  B. How much would she make if had 1, 3, 5, and 7 kids?

14 Joan gets paid $35 a day to watch kids and $5 per kid. Write a function that shows this.  A. What is the function equation of this problem? f(x) = 5(x) + 35

15 Joan gets paid $35 a day to watch kids and $5 per kid. Write a function that shows this. B. How much would she make if had 1, 3, 5, and 7 kids? f(x) f(x) = 5(x) + 35 F(x) = 5(x) + 35F(x) = ?( ) F(1) = 5(1) + 35F(1) = 5 + 35 = 40(1, 40) F(3) = 5(3) + 35F(3) = 15 + 35 = 50(3, 50) F(5) = 5(5) + 35F(5) = 25 + 35(5, 60) F(7) = 5(7) + 35F(7) = 35 + 35(7, 70)

16 F(x) = 4x 4(x) xy 4(-2) = -8-2-8 4(-1) = -4-4 4(0) = 000 4(1) = 4(2) = 4(3) = 4(4) =

17 F(x) = 4x 4(x) xy 4(-2) = -8-2-8 4(-1) = -4-4 4(0) = 000 4(1) = 414 4(2) = 828 4(3) = 12312 4(4) = 16416

18 Draw the following graphs

19 5. What is the slope of this graph?

20 6. What is the equation of this graph?

21 What is the slope of the following points? Show all work!!!  7. (-17, 5) (7, 11)  8. (-2, 13) (5, 9)

22 9. What is the slope and Y intercept of the Graph? What is a and b? xy -43 -20 0-3 2-6 4-9 6a 8b
