Question

Year of Experience Salary
1 $33,300
2 $33,450
4 $33,750
6 $34,050


The table shows the salary of an employee after x years of working for Company A. The linear function y = 200x + $29,000 represents the salary, y, of an employee in the same position working at Company B for x number of years. Which statement BEST compares the rate of change per year for the employee at Company A and the employee at Company B?

Answer 1

Company A's salary increases by $150 per year (from the table: +$150 each year). Company B's salary increases by $200 per year (slope of y = 200x + 29000). So Company B's rate of change is $50 per year greater than Company A's.
