In the last topic on graphing linear functions, we examined four distinct expressions of linear functions:
• Table of values (or solutions) • Graph • Equation (or “rule”) in mathematical symbols • Word problem
A single linear relationship may be expressed in any, or all, of these means.
Consider a waiter at a restaurant. The waiter is paid a flat, weekly salary of $100.00, and 80% of all the tips received (20% of the tips are reserved for the staff setting and cleaning the tables).
Using this word problem: (a) determine the equation of the function for the total weekly pay received by the waiter; (b) create a table of values; (c) plot selected values from your table; and (d) graph the function.
