Question

A surf instructor has an initial fee of $12 and charges $8

per hour for lessons.
Explain how to determine what the y-intercept is and
where it would be located on the graph.

Answer 1

y= 8x+12

Step-by-step explanation:

I have just completed it. Thank me later.

Answer 2

For this case we can define y as the response variable and represent the cost and x the independent variable who represent the hours of lessons. We know that the instructor has an initial fee of 12 and charges 8 per hour. So then we can model the situation with this formula:

`y =mx+b`

Where m = 8 represent the slope and b =12 the intercept so our model would be:

`y = 8x +12`

And the y intercept would be at x=0 and y=12 and represent the initial amount of money that we need to pay in order to have the instructor.
