You can start by getting your equation into the slope-intercept form: y = mx+b
x%2B2y+=+-6 Subtract x from both sides.
2y+=+-x-6 Divide both sides by 2.
y+=+%28-1%2F2%29x-3
Now you need only two points to draw the graph of a linear equation.
First. let x = 0 then solve for y.
y+=+%28-1%2F2%29%280%29-3
y+=+-3
First point is (0,-3)
Now let y = 0 and solve for x.
0+=+%28-1%2F2%29x-3 Add 3 to both sides.
3+=+%28-1%2F2%29x Multiply both sides by -2.
-6+=+x
Second point is (-6, 0)
Now plot these two point on your graph paper and draw a straight line through them. You should get the graph shown here:

x+2y=-6
2y=-x-6
y=-x/2-6/2
y=-x/2-3
you could set x=0 & solve for y
y=-0/2-3 then you have one point (0,-3)
then you could set y=0 & solve for x
0=-x/2-3
-x/2=3
-x=6
x=-6 then you have another point (-1.5,0)
