  1. Math CC8 – Be Prepared On Desk: Pencil/eraser Journal HW Tracking Sheet HW from Friday MSA Inv. Packet Journal: Date: 9/23 Title: MSA 4.2 Slope Formula Start the Entrance Ticket! Be ready to share your answers Reminder: MSA Test – Tues, Oct 1 HW Tracking Sheet: HW:MSA Packet p. 8 CHECK HW: Green

  2. Tasks for Today • Friday’s HW – Questions? • Warm Up • Lesson 4.2 – Finding the Slope of a Line • Begin HW

  3. Warm Up What is the slope and y-intercept of this line y = ½ x +3? Graph it. Now try this line: y= -2x -2

  4. Define all the parts of the equation. y = mx + b The dependent variable Y- intercept The independent variable Slope

  5. How do you find the slopefrom… • a graph? • Rise (vertical change) • Run (horizontal change) • a table? • As x goes up by 1, what happens to y? • an equation? • The coefficient • (the number next to the variable)

  6. In Packet Inv. 4 p.5

  7. Y-intercept = Y-intercept = 6 6 Slope = Rise = Run Slope = Rise = Run -3 1 3 1 Y = 6 - 3x Y = 3x + 6

  8. Slope = Rise = change in Y = Run change in X Slope = Rise = change in Y = Run change in X Y-intercept = -1 Y = 1.5x - 1 3 2 -0.5 1 Y-intercept = 5 0 5 Y = -0.5x + 5

  9. 5 20 Y-intercept = Y-intercept = Slope = coefficient of x Slope = Slope = coefficient of x Slope = 2.5 -3

  10. Math CC8 – Be Prepared On Desk: Pencil/eraser Journal HW Tracking Sheet HW from Monday MSA Inv. Packet Journal: Date: 9/24 Title: MSA 4.2 Slope Formula continued Reminder: MSA Test – Tues, Oct 1 HW Tracking Sheet: HW:MSA Packet p. CHECK HW: Red or Yellow

  11. Tasks for Today • Monday’s HW – Questions? • Warm Up • Lesson 4.2 – Finding the Slope of a Line • Begin HW

  12. -1 Make a table? Slope = Rise = change in Y = Run change in X Graph the points? Or calculate the change in y divided by the change in x (4, 4) (5, 3) (6, 2) Use the table to find 2 more points? Find the y-intercept , write the equation, use substitution?

  13. Skip?

  14. a graph? • Rise (vertical change) • Run (horizontal change) • a table? • As x goes up by 1, what happens to y? • an equation? • The coefficient • (the number next to the variable)
