It took them 4 days to install 480 chairs which means if they were working at a constant rate they got 120 chairs installed daily. with 360 chairs left that means in 3 days they will finish. so overall, it took the workers 7 days to finish, or a week.
6x + 12y = 7
12y = -6x + 7
y = -6/12 + 7
y = -1/2 + 7
the slope of the equation is -1/2
