Standard 3.0: Students graph and interpret linear and non linear functions
3.3 Graph linear functions, noting that the vertical change (change in y-value) per unit of horizontal change (change in x-value) is always the same and know that the ratio ("rise over run") is called the slope of a graph.
3.4 Plot the values of the quantities whose ratios are always the same. Fit a line to the plot and understand that the slope of the line equals the quantities.
