1. Bellwork Wednesday, November 10th
1) Describe how you find the slope of a line.
2) 33% of my free time during the day is spent putting grades in my gradebook. If I spend 20 minutes putting grades in my gradebook, how much free time do I have?

2. Writing and Graphing Linear Equations
Section 5 - Identifying Linear Functions
Section 6 - Intercepts
Section 7 - Rate of Change and Slope
Section 8 - Slope-Intercept Form
Section 9 - Parallel and Perpendicular Lines
Section 10 - Writing a Linear Equation Given Two Points
Section 11 - Translating Linear Functions 2 2

3. What we learned yesterday…
Finding slope from a GRAPH
slope can be positive, negative, zero, or undefined
you have to pick two points first
go up or down first
go left or right second
write your answer as a fraction

4. YOU TRY

5. x y What will this graph look like? Ex #1 Finding slope from a TABLE-1 2 4 1 6 +2 +1 +2 +1 +2 +1
What will this graph look like?
Ex #1

6. x y What will this graph look like? Ex #2 Finding slope from a TABLE 77 1 4 2 3 -2 +1 -3 +1 -3 +1 -3
What will this graph look like?
Ex #2

7. x y x y What will these graphs look like? YOU TRY
Find the slope. NO ARROWS = NO CREDIT.
1) 2) x y -3 99 98 3 97 6 96 x y 2 8 4 12 6 16 20
What will these graphs look like?

8. Sometimes isn’t so easy…x y
(-1.3, 1.62)
(5.76, 4.1)

9. x y
-1.3
1.62
5.76
4.1
+7.06
+2.48
(-1.3, 1.62)
(5.76, 4.1)

10. x y What will this graph look like? Ex #3 28 52 8 1 -20 -51
Find the slope of the line that contains (28, 52) and (8, 1). x y 28 52 8 1
-20
-51
What will this graph look like?
Ex #3

11. x y What will this graph look like? Ex #4 -8 232 95 +0 -137
Find the slope of the line that contains (-8, 232) and (-8, 95). x y -8
232 95 +0
-137
What will this graph look like?
Ex #4

12. What will this graph look like? What will this graph look like?
#1 Find the slope of the line that contains
(-20, -2) and (71, -2).
What will this graph look like? OR
horizontal
#2 Find the slope of the line that contains
(53, -7) and (6, -47).
What will this graph look like? OR
rise from left to right
#3 Which line is steeper?
#2 will be steeper
