As you can see, the equation is very nearly in standard form for a linear equation. This makes it extremely simple to graph, even more so than when the equation is in slope-intercept form.
The first thing to do is change it to standard form, Ax + By = C. You can do this by subtracting 6 from both sides of the equation to get:
2x - 3y = -6
Since this is a linear equation, all you need is two points to graph the whole thing.
The easiest two points to use are the x-intercept and y-intercept.
To find those two points, plug in 0 for one of the variables and solve for the other variable. This finds the x value when the y value is zero, and the y value when the x value is zero.
In this particular example:
2(0) - 3y = -6
-3y = -6
y = 3, when x = 0
2x - 3(0) = -6
2x = -6
x = -3, when y = 0
Now you have the two intercepts, you can easily graph the rest of the equation by connecting the two points.

This can be tranfered to:
2x-3y=-6
-3y=(-6-2x)
y=(-2x-6)/-3
y=2/3x+2
Type this into your graphing calculator, or add in x values to solve for y.
