Find Constant Of Proportionality (Graphs) Worksheet

1 problems

In a graph, the constant of proportionality, also known as the slope or rate of change, is the ratio of the change in the y-coordinate (the dependent variable) to the change in the x-coordinate (the independent variable) of a linear equation. It is represented by the letter "k" in the equation y = kx + b, where y and x are the coordinates of the points on the graph, k is the constant of proportionality, and b is the y-intercept.

Rates And Proportional Relationships

For example, if the line of a graph passes through the points (2, 4) and (5, 8), the slope of the line can be calculated as:

(8 - 4) / (5 - 2) = 4 / 3


The constant of proportionality is therefore 4/3, and the equation of the line is y = (4/3)x + b

Teaching Find constant of proportionality (graphs)  Easily


  1. Using real-world examples: Provide students with real-world examples of situations that involve proportional relationships, such as rates of speed, unit rates, and scale drawings. This can help students understand the concept and apply it to new situations.
  2. Graphing: Have students graph proportional relationships, and have them find the constant of proportionality by finding the slope of the line.
  3. Guided practice: Provide students with guided practice problems that involve finding the constant of proportionality in a graph.
  4. Worksheets: Continuously monitor student progress by using worksheets. This can help identify areas where students need additional support.
