To identify: The independent and dependent variables for each relation, used in the given graph.
Answer to Problem 23PPS
In given relation, independent variable is“ Number of dogs walked” anddependent variable is “Amount earned ( in dollars )”.
Explanation of Solution
Given information:Given relation as shown in the below graph under the topic, “Dog walking”
Concept used: In any graph, dependent variable is represented on vertical y axis and independent variable is represented on horizontal x axis.
Calculation:Values on x axis, represent number of dogs walked and the values of y axis, represent amount earned (in dollars) by walking these dogs. So, given graph shows that as the number of dog walked increase, the amount earned also increase simultaneously.
Conclusion: So, in above relation, independent variable is “Number of dogs walked.” and dependent variable will be, “total amount earned in dollars”.
