Quizplus · Accepted Answer

The independent variable is typically the one that is manipulated or controlled, which in this case is "hours studied." The vertical intercept (y-intercept) is the value of the dependent variable (quiz score) when the independent variable (hours studied) is zero, which is given as y = 2. The slope of the line indicates the change in the quiz score per hour studied, which is +2.
