This topic focuses on determining the run of a line, which is the horizontal change (change in x-values) between two points given specific inputs and outputs (function values) of y = f(x). Skills emphasized include understanding the relationship between coordinates, interpreting the meaning of 'run' in the context of line equations, and applying these concepts to calculate intervals between x-values in the context of graphing and linear equations. Questions provide pairs of x-values with corresponding y-values and ask for the change in x. Multiple choice answers are available for each question.
