Suppose It Has Been Established That "Annual Income" and "Years $= \$ 23,400 + \$ 7200$

Suppose it has been established that "annual income" and "Years of college" are linearly related, and that the relationship can be modeled using the following equation:
Annual Income $= \$ 23,400 + \$ 7200$ (Years of College $)$ . In this model, "Annual Income" is the $\frac{?}{}$ variable, and "Years of College" is the $\frac{?}{}$ variable, The two variables have a $\frac{?}{}$ linear relationship.
