Learning goals: Teacher Facing Comprehend that the points that lie on the graph of an equation represent exactly the solution set of the equation of the line (i.e., that every point on the line is a solution, and any point not on the line is not a solution). Create a graph and an equation in the form $Ax+By=C$ that represent a linear relationship. Determine pairs of values that satisfy or do not satisfy a linear relationship using an equation or graph.
