Plot the point (2,1)

 

Plot the point 3 left and 2 up from it, i.e. (-1,3)

 

Draw a line through those two points.

 

The point 3 right and 2 down works as well, i.e (5,-1)

More generally, if you want the equation of the line in the form y = mx + c, then m = -2/3 and you find c from: 1 = -(2/3)*2 + c   (so c = 7/3).
