Proportionality. The student applies mathematical process standards to explain proportional and non-proportional relationships involving slope.

8.4.AUse similar right triangles to develop an understanding that slope, m, given as the rate comparing the change in y-values to the change in x-values, (y2 - y1)/ (x2 - x1), is the same for any two points (x1, y1) and (x2, y2) on the same line.8.4.BGraph proportional relationships, interpreting the unit rate as the slope of the line that models the relationship.8.4.CUse data from a table or graph to determine the rate of change or slope and y-intercept in mathematical and real-world problems.
