Chart and Regression analysis :

What does the intercept predict?

X: C20 (annual number of training hours) versus Y: C21 (time to serve customers in minutes)

Equation:Y=0.0002x +21.6

Slope:0.002

Intercept:21.6

Does the intercept mean the intercept is 21.6 represents time to serve customers (Y) would be predicted number of the annual number of training hours(X) , but this intercept has no meaning. So, I will not use to predict time to serve customers in minutes?
