For each situation, graph the function and describe the key characteristics.

B. Franc earns $15 an hour as a delivery driver. His company also pays him $30 a week for car maintenance. What is the function that describes Franc's weekly earnings?

1) What is the rate of change for this situation? Be sure to include the units.
2) What is the independent quantity for this function?
3) What is the dependent quantity for this function?
4) Is the constant rate of change increasing or decreasing?
5) How do you know? Write your answer in terms of the independent and dependent quantities.
6) What is the slope of the function for this situation?
7) What is the Y- intercept of this function as it relates to the situation? Describe the y-intercept in terms of the function's independent and dependent quantities.
8) What is the ordered pair of the y-intercept?
9) Write the function equation in slope-intercept form.
10) Determine the zero of the function. Show your work.
11) Describe the x-intercept in terms of the function's independent and dependent quantities.
12) Fill in the table of values. Include the independent and dependent quantities and y-intercept. (TABLE IS ON PG. 3)
13) Graph the function equation on the coordinate plane. Include the following parts with your graph:
a. Provide scales and label for both axes.
b. plot at least three points, including the y-intercept.
c. Connect at least two points with the stair of the slope
d. Draw a straight line through the points using a straightedge.
14) Describe what would happen to the graph if Franc received a weekly increase and got $35 a week.
15) Describe what would happen to the graph if Franc earned $16 an hour instead of $15.
