Answer:
10
Explanation:
Given that the local ice cream shop is deciding whether or not to hire a new worker. The shop must pay the worker hourly and cover a daily cost for insurance. The cost to pay an hourly worker for one day is represented by the function y=10x+30 where x=hours.
We find that this is of the form y = mx+B where
m=10 and B =30
Hence slope =m =10
Answer is 10
and it represents the rate of change of y for a unit change in x.
