How Do You Find The Direct Proportion?

Direct proportion involves multiplicative reasoning. Direct proportion requires the student to work comfortably with fractions and decimals. The direct proportion statements below show y as proportional to x. When y is proportional to x it is written as y = kx, y is proportional to the square of x is written as y = kx2 , y is directly proportional to x cubed is written as y = kx3 , y varies directly with the square root of x is written as y = k√x.

What Is Direct Proportion Examples?

Directly proportional relationships are linear. When mapped on a graph if x and y are proportional, then the line formed is linear and straight through the origin. An example of directly proportional relationships when y is written in terms of x include: y = 1, x = 5, y = 2, x = 10, y = 3, x = 15. In this case the constant of proportionality is 5, where y = kx. The formula for this relationship is y = 5x. The graph circled below shows the shape of direct proportionality.
