Answer:
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.
