10. What is an equation that represents the cost, y, of the boat rental in terms of x hours?
11.What s the cost of a rental for 3 hours? Show your work
PLEASE BE CERTAIN WITH YOUR ANSWER!!!THX

10. y=15x+35?

11. The cost would be $80

Step-by-step explanation:

y=mx+b

y=(15x3)+35

y=45+35

y=80

Slope is 15 and y-intercept is 35.

Step-by-step explanation:

Given : The lake side marina charges a $35 rental fee for a boat in addition to charging $15 an hour for usage.

The total cost y of renting a boat for x hours can be represented by the equation  

To find : Graph the equation and interpret the slope and the y-intercept?

Solution :

The general slope form is  

where, m is the slope and c is the y-intercept.

On comparing the equation  

The slope is m=15.

The y-intercept is c=35.

Now we plot the equation  in graphing tool.

The equation is in green line passing thorough (35,0) and (-2.333,0).

Refer the attached figure below.

center= (-2,0)

radius= sqrt2/2
