This one-page graphing worksheet is designed to help eighth-grade math learners connect the constant of proportionality with the slope of a line. The worksheet includes four real-world scenario-based word problems, each featuring a proportional relationship. Students are required to graph the relationships by plotting at least three points and connecting them with a line. Then, they should write the slope in its simplest form. For a warm-up, students can try the "Graphing Proportional Relationships" worksheet. For further practice, students can move on to "Graph Proportional Relationships #2."
