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.

at time t = 1 hr... fee is initial ($12)+ ($8) = 20 
and so on... the intercept would be initial fee... which is $12 charged at t=0 hr

8$ per hour is the essentially the slope 
12 is the initial charge also known as the y-intercept 

y = 8x + 12 

where y is the total charge and x is the number of hours 
hope it helps

Answer:

The y-intercept in slope-intercept form is b, which is represented by 12. The y-intercept is the initial value, and is found on the graph as the point (0, 12) where the line crosses the y-axis.
