Hi
Using the standard slope-intercept form for an equation of a line y = mx + b
  where m is the slope and b the y-intercept. 
-X+3Y+6=0   |expressing in terms of Y
  Y = (1/3)X +2  |slope m = (1/3) and y-intercept is Pt(0,2)
Note: as y increases/decreases by 1, x increases/decreases by 3
Plot Pt(0,2) and Pt(3,3) and connect with a line
