This seventh- and eighth-grade math worksheet provides students with ample practice identifying the constant of proportionality from a graph. To determine the constant of proportionality, students need to select a point on the graph and then calculate the ratio of the y-coordinate to the x-coordinate. Students are required to find the constant of proportionality for several graphs in this two-page exercise, writing their answer as a whole number or simplified fraction. This worksheet is an excellent way to prepare students to solve problems involving real-world proportional relationships. For additional practice, students can try the "Find the Constant of Proportionality From Graphs" worksheet.
