Chapter 4 - Objectives

• Model data on the Cartesian coordinate system (for example: line graphs, bar graphs, and
  histograms) using appropriate scale and be able to explain why this is important;
  
• Differentiate between the independent and dependent variables in Cartesian graphs and
  assign these distinctions to the variables described in the context of the problem;
  
• Describe slope and rate of change, how these are related to graphs of lines, and what they
  represent in the context of the problem;
  
• Find the equation of any straight line using slope/intercept, point/slope, and standard forms of a line
