Quizplus · Accepted Answer

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