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?
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
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
YOU TRY
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
x y What will this graph look like? Ex #2 Finding slope from a TABLE 7 7 1 4 2 3 -2 +1 -3 +1 -3 +1 -3 What will this graph look like? Ex #2
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? YOU TRY
Sometimes isn’t so easy… x y (-1.3, 1.62) (5.76, 4.1)
x y -1.3 1.62 5.76 4.1 +7.06 +2.48 (-1.3, 1.62) (5.76, 4.1)
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
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
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 YOU TRY
