Write the various forms of equation of a straight line.

Slope-Intercept form:

y=mx+c\,

Ponit-Slope form:

y-y_{1}=m(x-x_{1})\,

Two Point form:

y-y_{1}={\frac  {y_{2}-y_{1}}{x_{2}-x_{1}}}(x-x_{1})\,

Intercepts form:

{\frac  {x}{a}}+{\frac  {y}{b}}=1\,

Normal form:

x\cos \alpha +y\sin \alpha =p\,

Symmetric form:

{\frac  {x-x_{1}}{\cos \theta }}={\frac  {y-y_{1}}{\sin \theta }}\,
