Question

Identify the independent and dependent variables for the relation.

Step-by-Step Solution

Answer

In given relation, the independent variable is “Number of dogs walked” and the dependent variable is “Amount earned (in dollars)”.

Step 1. Given Graph.

Given information: Given relation as shown in the below graph under the topic, “Dog walking”

Step 2. Concept Used.

In any graph, the dependent variable is represented on the vertical y-axis and the independent variable is represented on the horizontal x-axis.

Step 3. Calculation.

Values on the x-axis, represent the number of dogs walked and the values of the y-axis, represent the amount earned (in dollars) by walking these dogs. So, the given graph shows that as the number of dogs walked increase, the amount earned also increase simultaneously.

Step 4. Conclusion.

So, in the above relation, the independent variable is “Number of dogs walked.” and the dependent variable will be, “total amount earned in dollars”.
