# Identifying Proportional Relationships Worksheet

The constant value of the ratio between two proportional quantities is known as the proportional relationship. It is often termed the ‘constant of proportionality. Whenever variables are indirectly or directly proportional to each other, their relationship is represented as y = k /x or y = kx. Here, K is the constant of proportionality or proportional relationship. Constant of Proportionality is used to determine the rate of change.

## Teaching Identifying Proportional Relationship

• Direct Variation: Y = kx is the equation used to represent the direct variation. In this case, both x and y increase at the same rate.

• Inverse Variation: Y = k / x is the equation used to represent the inverse variation. In this case, y increases and x decreases. This can be the opposite too.

• In both cases, K is the constant of Proportionality.

Here is an example to solve a problem on identifying proportional relationships. Let’s look at the given example below to understand more about the concept.

Q. Identify the constant of proportionality, if  y = 27 and x = 3 and y ∝ x.

Step 1: Write the Equation of the proportional relationship.

So, y = kx.

Step 2:  Put the values and simplify the equation.

27 = k * 3

K = 27 / 3.

K = 9.

Hence, the constant of proportionality is equivalent to 9.
