Income and Consumption Relationship

• Variables:

  • Explanatory Variable (X): Income
  • Dependent Variable (Y): Consumption

• Slope (b):

  • Indicates strength of relationship between X and Y.
  • Can be described as strong or weak.

• Interpretation of Slope (b = 0.99):

  • Strong relationship: For every R1 increase in income, consumption increases by R0.99.

• Social Income Example:

  • If households receive R10,000 as social income, they consume R9,000, suggesting high consumption relative to income.

• Purpose of Equations:

  • Equations describe the story behind the data regarding income and consumption behavior.
