Graphing, Slope, And Special Lines Graphing, Slope, And Special Lines Presentation Transcript

  • Graphing Linear Equations: Slopes
  • Do Now: Using your calculator to help, graph the line y = 2x - 4
    • 1. Copy the table from the calculator
  • Do Now: Using your calculator to help, graph the line y = 2x - 4
    • Plot the (x,y) points. Remember start at the origin (the point where the x and y axes intersect – coordinates are (0,0) ) Go right (positive) or left (negative) first (x) and then up (positive) or down (negative) next (y).
    • Connect the points using a straight edge .
    • *** How do we know the graph should be a straight line?
  • Graph y = - 3x + 2 Graph y = ½ x - 4
  • What do the numbers in the equations represent?
    • y = mx + b
    • Where
    • m = the slope of the line
    • b = the y-intercept
  • How can we determine the slope of a line?
    • Find the slope of the line in the graph:
    • Pick two points on the line
    • Use the slope formula
  • Practice – Find each of the following slopes
  • Practice finding slope with no graph:
    • Find the slope of the line passing through (2,1) and (-3,-1)
    • Find the slope of the line passing through (-2,3) and (-4, 0)
  • Special Lines: Find the slope of each of the following Conclusion: Conclusion:
  • Special Lines:
    • Horizontal Lines:
    • Slope is
    • Equation is
    • Vertical Lines:
    • Slope is:
    • Equation is:
  • Graph each of the following pairs of lines. What do you observe?
    • a. y = 2x + 3 What do these lines have in common?
    • b. y = 2x – 1
    • a. y = - 3x – 2 What do these lines have in common?
    • b. y = - 3x + 3
    • a. y = ½ x – 3 What do these lines have in common?
    • b. y = ½ x + 5
    • CONCLUSION:
  •
