Understanding Perpendicular Slopes

The video tutorial explains how to find the slope of a line perpendicular to a given line. It begins by introducing the concept of perpendicular slopes and the importance of negative reciprocals. The tutorial then demonstrates how to convert a linear equation into slope-intercept form to easily identify the slope. Finally, it calculates the slope of a line perpendicular to the given line by taking the negative reciprocal of the original slope.

What is the first step in finding the slope of a line perpendicular to another line?

• Find the slope of the given line

• Determine the x-intercept

• Identify the y-intercept

• Calculate the midpoint
