Abike rental company charges a $5 service fee and $1 per hour. if this situation is represented as a function, what would be the slope?

Write as a function equation: where f(x) is the same as "y"

f(x) = 5 + 1x    y = 1x + 5

Use:  y = mx + b  (Where m = slope and b is y intercept)

Slope is 1 and y intercept is +5 

Remember slope is rise over run so 1 can be written as 1 / 1 and interpreted as rise 1 and run 1 both in the positive direction. 

3x+9+4x+x=8x+9that's the answer for your question.
