Solve the problem.The amount of water in a leaky bucket is given by the linear function 
, where y is in ounces and x is in minutes. Find and interpret the slope and y-intercept of the linear equation.
A. m = 121; The amount of water in the bucket increases 121 ounces every minute. 
At x = 0, the amount of water in the bucket was 11 ounces.
B. m = -11; The amount of water in the bucket decreases 11 ounces every minute. 
At x = 0, the amount of water in the bucket was 121 ounces.
C. m = 11; The amount of water in the bucket increases 11 ounces every minute. 
At x = 0 the amount of water in the bucket was 121 ounces.
D. m = 121; The amount of water in the bucket decreases 121 ounces every minute. 
At x = 0, the amount of water in the bucket was 11 ounces.
