In the graph, the five points show the money earned versus time
worked for each of five employees. Each was paid a different but fixed
number of dollars per hour. Which letter represents the employee who was
paid the most money per hour?

Pick one
Solution
The vertical axis represents money earned (in dollars) and the
horizontal axis represents time (in hours).
Thus, each employee’s money earned per hour is the slope of the line
segment from the origin to
the employee’s letter.
The employee who was paid the most money per hour is the employee
whose line segment has the greatest slope.
The line segment with the greatest slope is the steepest of the line segments, and so Employee was paid the most money per hour.
Alternately, we could add numbers to each of the axes and use them to
determine the slope of each line, and thus the money earned per hour for
each employee.
