Writing equations for Linear Functions

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
