Friday, March 23 rd. Warm Up. Please have Graphing worksheet out!. If a point on a direct variation graph is (5,6), what is k? 2. What point does a direct variation graph have to go through?. Corny of Joke of the Day. Why did Wesley start a lawn care service?

Do You Remember? • Which axis is the horizontal axis? _____________ • Which axis is the vertical axis? _____________
Goal for Today Finding K on a graph
Direct Variation
K= Slope When you think of the word SLOPE…what do you think of?!
The slope we are studying is associated with the graph of a line
Different Slopes zero Positive Undefined Negative
Zero Slope“Not Much Happening” Horizontal Line
We will only be working with POSTIVE SLOPES that go through the point (0,0)
K= Rise ÷ Run Rise= y axis Run= x axis
What goes first? You need to rise up before you run
Finding Slope “The Meat of it”
#1 Slope:
#2 Slope:
#3 Slope:
#4 Slope:
SO. . . If you graphed each set of equations below, all of the graphs would be straight lines. For each group of equations, the steepest line would be represented by which equation? • y = 3x B. y = 9x Cy = x D. y = 4x
