Constant of Proportionality Worksheets

The constant of proportionality is the ratio between two variables y and x. Interpret the constant of proportionality as the slope of the linear relationship y = kx. Find the proportional relationship between x and y values to solve this set of pdf worksheets that comprise graphs, equations, and tables. Students will also learn to find the missing values in tables based on the constant of proportionality k, so derived. These printable worksheets are specially designed for students of grade 7 and grade 8. Click on the 'Free' icon to sample our worksheets.

Constant of Proportionality - Graph

7th grade students should use the slope of each graph to identify the constant of proportionality, k. Then, find the proportional relationship between the x and y coordinates by applying the formula y = kx.
