Annie owns a tutoring service. For each tutoring session, she charges $75 plus $35 per hour of work. A linear equation that expresses the total amount of money Annie earns per tutoring session is y=75+35x . What are the independent and dependent variables? What is the y -intercept and the slope? The independent variable (x ) is the amount of time Annie tutors. The dependent variable (y ) is the amount, in dollars, Annie earns for a tutoring session.
