So first divide the equation on both sides by 3. We get [tex]x - 2y = 4
[/tex]. Slope-y-intercept form is of the form [tex]y = mx + b[/tex]. Rearranging [tex]x - 2y = 4
[/tex], we get [tex]2y = x - 4[/tex]. Divide by two, we get [tex]y = \frac{x}{2} - 2 [/tex], which is of that form.
Graphing: The y intercept is at -2, and the slope is 1/2.
