Example Question #7 : How To Find The Slope Of A Perpendicular Line

A line is defined by the following equation:

What is the slope of a line that is perpendicular to the line above?

Possible Answers:

Correct answer:

Explanation:

The equation of a line is  where  is the slope.

Rearrange the equation to match this:

For the perpendicular line, the slope is the negative reciprocal;

therefore 

Example Question #2 : How To Find The Slope Of Perpendicular Lines

Find the slope of the line perpendicular to the line that has the equation .

Possible Answers:

Correct answer:

Explanation:

Perpendicular lines have slopes that are negative reciprocals of each other. In other words, change the sign and flip the fraction around.

Example Question #3 : How To Find The Slope Of Perpendicular Lines

Find the slope of a line perpendicular to the line with the equation .

Possible Answers:

Correct answer:

Explanation:

Perpendicular lines have slopes that are negative reciprocals of each other. In other words, change the sign and flip the fraction around to find the slope of the line perpendicular to the given one.
