Solve the problem.After two years on the job, an engineer's salary was $55,000. After seven years on the job, her salary was $64,000. Let y represent her salary after x years on the job. Assuming that the change in her salary over time can be approximated by a straight line, give an equation for this line in the form y = mx + b.
A. y = 9000x + 37,000 B. y = 9000x + 55,000 C. y = 1800x + 51,400 D. y = 1800x + 55,000
