Students solve multistep equations (with variables on only one side).  Students choose between two models/equations at each of six points in this Google Form activity.

This task requires students to use the fact that on the graph of the linear function h(x)=ax+b, the y-coordinate increases by a when x increases by one. Specific values for a and b were left out intentionally to encourage students to use the above fact as opposed to computing the point of intersection, (p,q), and then computing respective function values to answer the question. The Virginia Department of Education resource titled, "Graphing Linear Functions," which requires students to graph equations in y=mx + b form includes a template and lesson plan.
