Discrete Data and Plotting It

Now that we are pros at graphing linear equations and determining the slope of lines, we looked at real life problems that are similar to linear equations but produce answer sets that involve discrete, or specific, non-continuous, data points. Examples include the number of nickels you can have (you can only have a whole number of nickels, not 1.5 or 3.82 nickels). When plotting these discrete data points, the graph looks like a group of dots that describe a line. The term "domain" refers to the values along the x axis, while the term "range" refers to the values along the y axis.

Tonight's homework: Complete the two worksheets: "Nickels and Dimes" and "Candy Combinations".
