Using point slope form find a perpendicular line through a point

The video tutorial explains how to find a line that is perpendicular to a given line and passes through a specific point. It begins by introducing the problem and discussing the concept of perpendicular lines having opposite reciprocal slopes. The tutorial then guides viewers through calculating the new slope, forming the equation, and solving for the Y-intercept using the given point. Finally, it demonstrates how to finalize the equation for the perpendicular line.

Explain the process of using the slope-intercept form to find the equation of a line.
