Question

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 y=15x+35? graph the equation?

interpret the slope and the y-intercept?

Answer 1

y=15x+35

Explanation:

Answer 2

Slope is 15 and y-intercept is 35.

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
`y=15x+35`

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

Solution :

The general slope form is
`y=mx+c`

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

On comparing the equation
`y=15x+35`

The slope is m=15.

The y-intercept is c=35.

Now we plot the equation
`y=15x+35` in graphing tool.

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