Identify the slope, y-intercept, and whether the line is increasing or decreasing. 

• Slope = 2
  Y-int = (0, -2/3)
  Increasing

• Slope = -2/3
  Y-int = (2, 0)
  Decreasing

• Slope = -2/3
  Y-int = (0, 2)
  Decreasing

• Slope = -2/3
  Y-int = (2, 0)
  Decreasing

Identify the slope, y-intercept, and whether the line is increasing or decreasing. 

• Slope = -9
  Y-int = (0, 2)
  Decreasing

• Slope = -9
  Y-int = (0, 2)
  Increasing

• Slope = 9
  Y-int = (0, 2)
  Decreasing

• Slope = 2
  Y-int = (0, -9)
  Increasing

Identify the slope, y-intercept, and whether the line is increasing or decreasing.

• Slope = -1/4
  Y-int = (0, 8)

  Y-int = (0, 8)
  Decreasing

• Slope = 1/4
  Y-int = (0, 8)
  Increasing

• Slope = 8
  Y-int = (0, 1/4)
  Increasing
