Allison rents a musical instrument. This graph shows the cost to rent the instrument for different lengths of time. How can Allison show that the slope is constant and what that constant slope shows in this situation. Chose one option from each drop-down menu to answer the question.

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
