Hi,
find the slope and y intercept of the line and use the slope and y intercept to sketch a graph of the line.
  21x - 9y = 18
OR  y = (21/9)x - 18/9
    y = (7/3)x-2   m = 1/3 and y-intercept is (0,-2)
Note: as y increases/decreases by 7, x increases by 3.  Ex. (3,5) on this Line
{{{drawing(300,300,   -6, 6, -6, 6, grid(1),
circle(0,-2,0.3),
circle(3,5,0.3),
graph( 300, 300, -6, 6, -6, 6,0, (7/3)x-2))}}}
