Question

Part A: Sam rented a boat at $225 for 2 days. If he rents the same boat for 5 days, he has to pay a total rent of $480.

Write an equation in the standard form to represent the total rent (y) that Sam has to pay for renting the boat for x days. (4 points)

Part B: Write the equation obtained in Part A using function notation.(2 points)

Part C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals. (4 points)

Answer 1

So we'll write it in point-slope form first, then convert it into standard form.

Answer 2

So find out the slope first

Answer 3

The slope of a function is rise over run, or y-distance/x-distance, or in this context "the increase of rent over the increase of number of days"

Answer 4

Please be noted that I'm talking about "the increase" instead of the actual amount
