\

The slope - intercept form of two line equations are \"\".

\

The above two lines are parallel, so their slopes are same.

\

Therefore \"\".

\

The slope - intercept form of line equation \"\" is perpendicular to the the above two line equations. \ \ The lines are perpendicular, so their slopes are negative reciprocals.

\

Therefore slope of perpendicular line is \"\".\"\"

\

The slope - intercept form of two parallel lines are \"\" and the slope - intercept form of perpendicular line is \"\".
