Geometry: How do we write the equations of perpendicular lines?

Geometry:  
Investigate the slopes of perpendicular lines. Write the equation of a line perpendicular to an original line through a given point. Use the opposite reciprocal slope and the point to find the appropriate y-intercept. Perpendicular lines do not have the same slopes.
