Identifying and Writing Equations of Perpendicular Lines

This video tutorial teaches how to identify and write equations of perpendicular lines by focusing on their slopes and y-intercepts. It explains the concept of perpendicular lines intersecting at right angles and demonstrates how to determine their equations using examples. The tutorial covers converting equations to slope-intercept form, using point-slope form for writing equations, and applying these concepts in geometry problems involving shapes like parallelograms.

Explain how to write the equation of a line that is perpendicular to a given line.

What is the equation of the line opposite the base of a parallelogram given its slope?
