Question

James just began a job as a nurse. He is given a starting salary of $66,640 per year. He is also told that his salary will increase to $73,400 in 8 years. Assume that x = the years worked and y = Salary in dollars. Using this information, find the following answers:

What is the rate of change of James’ salary?
Instructions: Find the slope by first creating two points in the form (years, salary), and then calculate the slope using the correct slope formula.

Answer 1

Find the slope by first creating two points in the form (years, salary)

(0, 66640) ; (8, 73400)

calculate the slope using the correct slope formula

m = (73400 - 66640)/(8 - 0) = 6760/8 = 845
