Question 12572
You first need to get 2X + Y = 6 into slope intercept form which is y = mx+b
<BR>
To do this you need to subtract 2X from both sides, giving you y = -2x + 6
<BR>
Now you know your y intercept = 6 and slope is -2
<P>
Your y-intercept is a point on the y axis, in this case 6, so go up 6 and plot the point (0,6), your slope, -2 should always be thought of as a fraction 
{{{rise/run}}} -2 as a fraction is {{{-2/1}}} so your rise is -2 and your run is 1
<P>
a rise of -2 means go down on the y-axis 2 units, and since you always run right, you move 1 unit along the x-axis, so you should now have a point at (1,4)
<BR>
Plot this point and connect your two points, thus creating a graph, it should look like the one below
<P>

{{{ graph(300,200,-3, 10, -3, 10, -2x+6)}}}
