10. Whip Around
List the characteristics of liner functions

11. Bondi Beach, Sydney, Australia

12. Learning Intention/Success Criteria
LI: We are learning how to graph linear equations SC: I know how to 1. approximate the slope of a linear function 2. distinguish/interpret between “m” and “b” in equations 3. understand what variables represent in word problems 4. graph x = c and know it’s not a function 5. graph y = c 6. graph in slope intercept form [f(x) = mx + b]

13. Vocabulary Revisited Slope: Indicates the steepness of a line
Indicates if a line is tilted uphill or downhill
Represented by the letter “m”
Y-Intercept:
The point at which the graph intercepts the y-axis
Represented by the letter “b”

14. Fold the the construction paper hot dog style

15. Create four sections by folding or measuring

16. Yay! Water slide!
Open the section we just worked on

17. This is just the top section!
Positive Slope

18. This is just the bottom section!
“m” is positive
This is just the bottom section!
Line goes upward from left to right when graphed
As the value of x increases, the value of y increases
Example: f(x) = 3x OR f(x) = 2x + 9

19. Yay! Water slide!
OMG! Scary!
Open the section we just worked on

20. This is just the top section!
Negative Slope

21. This is just the bottom section!
“m” is negative
This is just the bottom section!
Line goes downward from left to right when graphed
As the value of x increases, the value of y decreases
Example: f(x) = -3x OR f(x) = -2x + 9

22. Yay! Water slide!
OMG! Scary!
Boring!
Open the section we just worked on

23. This is just the top section! Zero Slope
SC6
Zero Slope

24. This is just the bottom section!
“m” is zero
This is just the bottom section!
SC6
Line goes horizontal from left to right
As the value of x increases, the value of y stays the same
Example: f(x) = 3 OR f(x) = 0x - 4

25. Yay! Water slide!
Ahhhh!
OMG! Scary!
Boring!
Open the section we just worked on

26. This is just the top section! Undefined Slope
SC4
Undefined Slope

27. This is just the bottom section!
SC4
“m” doesn’t exist
Line goes vertical from left to right
The value of x stays the same and the value of y increases
Not a function!
Example: x = -3 OR x = 4

28. Example 1: State the slope and y-intercept from the equation
Example 1: State the slope and y-intercept from the equation. Then, graph the equation
g(x) = -3x + 2
SC2 SC1 SC6
Slope: y-intercept:
-3/1 2 -3 1 1 -3

29. Guided Practice 1
State the slope and y-intercept. Then, graph the equation. Equation: d(r) = 2r –
Slope: y-intercept: 2 3
2/3 2 3 2 3 -7

30. Guided Practice 2
State the slope and y-intercept. Then, graph the equation. Equation: z(p) = -5p
Slope: y-intercept: -5
-5/4 4 -5 4

31. Example 2: Write the equation from the given graph
SC6 SC1
Slope: Y-Intercept: Equation: 2 5
f(x) = 2x + 5

32. Guided Practice 3 Find the equation from the given graph
Equation: Slope: Y-Intercept:
p(x) = -5 -5

33. Guided Practice 4 Find the equation from the given graph
Equation: Slope: Y-Intercept:
x = -5
Doesn’t exist
none

34. Jose will charge a base fee of $100 before working on the plumbing.
Example 3: Jose the plumber charges $65 per hour to fix your plumbing. He uses the equation, C(h) = 65h to determine the charge of his services, C, after working h hours.
What is the meaning of the y-intercept in context?
The y-intercept is 100.
SC2 SC3
Jose will charge a base fee of $100 before working on the plumbing.

35. Each hour Jose works, he charges $65.
What is the meaning of the slope in context?
The slope is 65.
SC2 SC3
Each hour Jose works, he charges $65.
