Question

Quizplus · Accepted Answer

The letter "a" represents the intercept of the equation, which is the value of y when x = 0. Therefore, choice D is the correct answer. Choice A is incorrect because the independent variable is represented by "x" in the equation, and choice B is incorrect because the dependent variable is represented by "y" in the equation. Choice C is incorrect because the slope of the equation is represented by "b".
