Answer:
[tex]y=\frac{1}{3} x-6[/tex]
Step-by-step explanation:
Write down the slope-intercept form:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
To turn the equation into slope-intercept form, isolate y on the left-hand side:
[tex]x-3y=18\\-3y=18-x\\y=-6+\frac{x}{3} \\[/tex]
Rearrange the equation a bit:
[tex]y=\frac{1}{3} x-6[/tex]
