[tex]\bf 3x-5y=30\implies 3x-30=5y\implies \cfrac{3x-30}{5}=y\implies \cfrac{3x}{5}-\cfrac{30}{5}=y \\\\\\ \stackrel{y-intercept}{\cfrac{3}{5}x-\stackrel{\downarrow }{6}}=y\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}~\hfill \stackrel{y-intercept}{(0,-6)}[/tex]
