f(h) = 250 +8.5h
The function is on slope-intercept form:
y(x)= mx +b
Where m is the slope.
Rearranging the function given:
f(h) = 8.5h +250
Where:
250 is the fixed commission since it doesn't have a variable next to it.
8.5 is the hourly wage.
We can see that the hourly rate (8.5 per hour) is the slope of the function.
