You can start by getting your equation into the slope-intercept form: y = mx+b
Subtract x from both sides.
Divide both sides by 2.

Now you need only two points to draw the graph of a linear equation.
First. let x = 0 then solve for y.

First point is (0,-3)
Now let y = 0 and solve for x.
Add 3 to both sides.
Multiply both sides by -2.

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)
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, -x/2 -3).
