Question 55070
First subtract 2x from both sides to get {{{-3y=-2x+12}}} and then divide both sides by -3 to get {{{y=expr(2/3)x-4}}}.  Now create two ordered pairs by substituting in values of x to determine y -- you decide the x values.  For example, if x=0, then y=-4; if x=3, then y=-2.  Plot those two points and connect via a straight edge.  The graph is:
{{{graph(200,200,-5,10,-5,5,2x/3-4)}}}
