  1. Friday, March 23rd 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?

  2. Corny of Joke of the Day Why did Wesley start a lawn care service? Because he wanted to “rake” in some cash

  3. March Madness

  4. March Madness Math CRCT: Grade 6 Thursday, March 22 March Madness Grade 6

  5. 7. Which method could be used to solve the number sentence shown?4x = 16A. Subtract 4 from 4x, and subtract 4 from 16B. Subtract 4 from 4x, and subtract 16 from 16C. Divide 4x by 4, and divide 16 by 16D. Divide 4x by 4, and divide 16 by 4 March Madness Grade 6

  6. 8. Which of the following nets can be folded along the dashed lines to form a cube? March Madness Grade 6

  7. March Madness Math CRCT: Grade 6 Friday, March 23 March Madness Grade 6

  8. 9. In a random survey, 25 out of 150 people were able to give a correct answer to the question asked. If 500 people are surveyed, about how many would be expected to answer the question correctly? • 4 C. 83 B. 20 D. 325 March Madness Grade 6

  9. 10. In which of the following tables does each pair of numbers (x,y) satisfy the equation x + 6 = y? March Madness Grade 6

  10. Homework Answers

  11. Where is the origin?!?!

  12. Do You Remember? • Which axis is the horizontal axis? _____________ • Which axis is the vertical axis? _____________

  13. How do you find k?

  14. Goal for Today Finding K on a graph

  15. Direct Variation

  16. K= Slope When you think of the word SLOPE…what do you think of?!

  17. Slopes are commonly associated with mountains

  18. The slope we are studying is associated with the graph of a line

  19. Different Slopes zero Positive Undefined Negative

  20. POSITIVE SLOPE“Reaching the Goal”

  21. Negative Slope“The Tumbler”

  22. Zero Slope“Not Much Happening” Horizontal Line

  23. We will only be working with POSTIVE SLOPES that go through the point (0,0)

  24. K= Rise ÷ Run Rise= y axis Run= x axis

  25. What goes first? You need to rise up before you run

  26. Finding Slope “The Meat of it”

  27. #1 Slope:

  28. #2 Slope:

  29. #3 Slope:

  30. #4 Slope:

  31. The steeper the line is the larger K will be!

  32. 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
