Write the equation of a line through a point perpendicular to another line

The video tutorial explains the concept of perpendicular lines and their slopes, focusing on the idea of opposite reciprocals. It compares perpendicular lines to parallel lines, which have the same slope, and provides an example to illustrate how to calculate the opposite reciprocal slope. The tutorial also demonstrates how to apply this concept to equations, emphasizing the importance of flipping the slope and changing its sign.

How can you rewrite a slope of 1 in fractional form?

If the slope of a line is 1/1, what would be the opposite reciprocal slope?
