11. Hobart, Tasmania, Australia

12. Learning Intention/Success Criteria
LI: We are learning how find the slope between two points SC: I know how to 1. find m from a table, graph, or ordered pairs 2. understand how the slope formula relates to the numeric representation of functions 3. identify x and y and use the slope formula 4. substitute values into equations or expressions 5. interpret what slope means in context

13. Today’s Vocabulary Slope Formula: m = change in y change in x
m = y2 – y1 x2 – x1

14. Vocabulary Revisited Slope: Indicates the steepness of a line
Indicates if a line is tilted uphill or downhill
Represented by the letter “m”

15. Example 1: Find the slope between two points: (3, -4) and (2, 5)
SC3 x1 y1 x2 y2
m = y2 – y1 x2 – x1
SC4
m = 5 – – 3
m = – 3
m =
= - 9
SC1 SC2

18. Guided Practice 1 Answers
Find the slope between the two points: (-4, 2) and (-6, -8)
m = y2 – y x2 – x1
m = -8 –
m = -8 –
m = – 2
= 5

21. Guided Practice 2 Answers
Find the slope between the two points: (8, -3) and (0, -1)
m = y2 – y x2 – x1
m = -1 – – 8
m = – 8
m = =

22. Example 2: Find the slope between two points: (5, 4) and (5, 1)
SC3 x1 y1 x2 y2
m = y2 – y1 x2 – x1
SC4
m = 1 – – 5
m =
m = undefined
SC1

28. Time (min) Distance (mi)
Example 3a: The table shows the number of miles a plane traveled while in flight. Use the table to find the rate of change.
Time (min)
Distance (mi) 3
27.5 12
110 66
605
164
1503.4 x1 y1 x2 y2
SC3
m = y2 – y x2 – x1
m =
m = 9.17
m = 605 – – 12
SC4
SC1

29. Example 3b: What does the slope mean in context? y x
SC5
y x
Miles Flown Minutes Flown
Miles Flown Minutes Flown
The plane flew 9.17 miles every minute

30. Exit Note/Quiz Find the slope of the line passing through the points:
1. (2, 1) and (0, 1) 2. (2, 5) and (2, 8) 3. (4, 2) and (8, 4) 4. (-6, 2) and (0, -6)
