The y-intercept is $-\frac{5}{3}$, and the slope is $\frac{1}{3}$.

We know that $y=mx+b$, where m is the slope and b is the y-intercept. We simplify the equation until it is in this form: $$x-3y=5 \\ -3y=-x+5 \\ y=\frac{1}{3}x-\frac{5}{3}$$ The y-intercept is $-\frac{5}{3}$, and the slope is $\frac{1}{3}$.
