The correct points represent the salary Mr. Brown makes after 3, 4, and 5 years, respectively. We use the given function s=1,500y+40,000 to find out the total salary for each year.
For the 3rd year:
s = 1,500(3) + 40,000
s = 4,500 + 40,000
s = 44,500
For the 4th year:
s = 1,500(4) + 40,000
s = 6,000 + 40,000
s = 46,000
For the 5th year:
s = 1,500(5) + 40,000
s = 7,500 + 40,000
s = 47,500
So, the correct points on the graph that represent Mr. Brown's salary after 3, 4, and 5 years are:
(3,44,500), (4,46,000), and (5,47,500)
