Use the equation for delivery costs below to answer the following. C = 0.45m + 6
(a) Give the slope of the equation. (Let C be the fee in dollars for special delivery m miles over the first 10 miles. Do not include units in your answer.
Explain the slope's meaning in this[situation. (Include units in your answer. More information.)
It means that each mile over
will increase the delivery fee by
(b) If the fees were changed to $7 for delivery and 65 cents for each mile over 10 miles, how will that change the appearance of the graph?
The graph will have a lower vertical intercept, and would increase at a higher rate.
The graph will have a higher vertical intercept, and would increase at a higher rate.
The graph will have a higher vertical intercept, and would increase at a lower rate.
