The equation is given as,
[tex]3x-y+2=0[/tex]For the polar form,
[tex]\begin{gathered} x\text{ = rcos}\theta \\ y\text{ = rsin}\theta \end{gathered}[/tex]Modifying the given equation,
[tex]3rcos\theta+2rsin\theta-5=0[/tex]Taking r common,
[tex]r(3cos\theta+2sin\theta)-5=0[/tex]Transposing 5 to R.H.S,
