There are no late fees. 1.Write a linear function to represent the amount of money you spend each month. 2.Graph the line and identify the y-intercept. 3.What does the y-intercept represent in the context of the problem? 4.What does the slope represent in the context of the problem? 2 3.9.1: Interpreting Parameters

3. 1.Write a linear function to represent the amount of money you spend each month. The independent variable represents the number of games rented each month. The price per game is $2. The constant value is the $5 monthly fee. The function in slope-intercept form is f(x) = 2x + 5. 3 3.9.1: Interpreting Parameters

4. 2.Graph the line and identify the y-intercept. The y-intercept is 5 and the slope is 2. Plot the point (0, 5) and then count up 2 spaces and over to the right 1 space to plot the next point (1, 7). Connect the points to draw the line. 4 3.9.1: Interpreting Parameters

5. 3.What does the y-intercept represent in the context of the problem? The y-intercept represents the membership fee, which is constant each month. 5 3.9.1: Interpreting Parameters

6. 4.What does the slope represent in the context of the problem? The slope represents the cost to rent each game. 6 3.9.1: Interpreting Parameters
