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 2

HI!!

Answer 3

what equation did you get?

Answer 4

Hi

Answer 5

looks good to me

Answer 6

y = 85x + 55 is in the form y = mx+b

m is your slope
b is the y-intercept

Since b = 55, this means you plot the point (0,55). Basically the point at 55 on the vertical y axis. This equation is a line, so you need 2 points. To get the next point, we use the slope

85 = 85/1 is the slope. The "85" up top means we move up 85 units, then we move 1 unit to the right to land on (1,140)

So this graph is a straight line that goes through (0,55) and (1,140)

Answer 7

slope is 85, y intercept is 55

Answer 8

@jim_thompson5910 described how to graph it i think

Answer 9

it is not that easy because the scale will have to be different for the y and the x

Answer 10

I am so confused

Answer 11

you know how to graph a line in general?

Answer 12

plot the y intercept which is 55

Answer 13

yes @misty1212

Answer 14

@jim_thompson5910 is graphing it

Answer 15

plot the point (1,140)

this point is found by going up 85 units, then to the right 1 unit
