Slope interpretation: if the percent of the population that is low income increase by 1, we would expect that the length of the school day will decrease by 0.0102 hours.
y-interpretation: when the percent of the population that is low income is 0 (or becomes very close to 0), we would expect that the length of the school day to be 7.11 hours.

For the slope, we could also have said that when the percent of the population that is low income increases by 1, the length of the school day decreases by 0.012 hours, on average.
It seems that there are no districts with exactly 0% low income residents, but for some of them the percent of the population that is low income is very close to 0.
