First of all, I would like to thank Cosmos for deleting my incorrect answer. (applause)
Now, we will proceed to our main program.
Manipulate -6y + 2x = 18 into the y = mx + b form.
Subtract 2x from both sides
-6y = -2x + 18
Divide both sides by -6
[tex]y = \frac{-2}{-6}x + \frac{18}{-6} [/tex]
Simplify
[tex]y = \frac{1}{3} x - 3[/tex]
The slope will be the coefficient of x.
[tex]The\ slope\ is\ \frac{1}{3} \ .[/tex]
