●      represent linear non-proportional situations with tables, graphs, and equations in the form of y = mx + b, b ≠ 0. 

●      use data from a table or graph to determine the rate of change or slope and y-intercept in real-world problems 

●      distinguish between proportional and non-proportional situations using tables, graphs, and equations in the form y = kx and y = mx + b, where b ≠ 0 

●      identify and verify the values of x and y that simultaneously satisfy two linear equations in the form y = mx + b from the intersections of the graphed equations
