Essay

For a day's work, Chris is paid $50 to cover expenses plus $16 per hour. Let x denote the number of hours Chris works in a day and let y denote Chris's total salary for the day. Obtain the equation that expresses y in terms of x. Construct a table of values using the x-values 2, 4, and 8 hours. Draw the graph of the equation by plotting the points from the table and connecting them with a straight line. Use the graph to estimate visually Chris's salary for the day if he works 6 hours.
