You can call year 2011 to be YEAR 0, and this gives a data point of (0,226). The slope is 18 in unit of STUDENTS per YEAR, and is positive. You can use the point-slope form equation for a line and say y-226=18%28x-0%29, and be reminded, this is for x to mean number of years after 2011.

The meaning for y is, number of students enrolled.
