Answer:
[tex]y=\frac{1}{2} x-3[/tex]
which looks like the second answer option you have listed
Step-by-step explanation:
In order to express a linear equation in slope-intercept form, one just needs to solve for "y" in the equation:
[tex]6y-3x=-18\\6y=3x-18\\y=\frac{3x-18}{6} \\y=\frac{1}{2} x-3[/tex]
