Leslie cleans the barns for the horses.  Her time spent cleaning can be modeled by the equation y = 15 x + 30, where x represents the number of stalls that contains horses.  What is the meaning of the y-intercept?

• The time it takes to clean one horse

• the time it takes to clean one stall

• the time it takes to clean an empty barn

• the times it takes to clean each of the stalls with a horse
