I just want to make sure I have this: Is the slope of the line determined by the equation 6x - 3y=18 m=2?
in general, equation of the line is in the form $\displaystyle y = mx + c$, where $\displaystyle m$ is the slope of the line.
in your case, $\displaystyle y= 2x - 6$, so yes,..the slope is $\displaystyle 2$
