Description: Identifying the dependent and the independent variables in a word problem. Created by Sal Khan. In the table above, q represents the number of questions that you answer correctly on your math quiz, and p represents the total number of points that you score on your quiz. The relationship between these two variables can be expressed by the following equation. p is equal to 5q, where p is the points you get and q is the number of questions you answered correctly.
