Question 284778
The easiest way is to find the intercepts.
Those are the points that intersect the x and y axis. 
To find the x-intercept, set y=0 and solve for x.
{{{6x-2y = 12 }}}
{{{6x-2(0)=12}}}
{{{6x=12}}}
{{{x=2}}}
Plot the point (2,0).
{{{drawing( 300, 300, -10, 10, -10, 10,grid( 1 ),circle(2,0,.2),circle( 2, 0, .35))}}}

To find the y-intercept, set x=0 and solve for y.
{{{6x-2y = 12 }}}
{{{6(0)-2y=12}}}
{{{-2y=12}}}
{{{y=-6}}}
Plot the point (0,-6).
{{{drawing( 300, 300, -10, 10, -10, 10,grid( 1 ),circle(2,0,.2),circle( 2, 0, .35),circle(0,-6,.2),circle( 0, -6, .35))}}}

For a line, you only need two points. 
Connect those two points with a line that goes through both.
