What is the slope of a line that is perpendicular to the
To find: The slope of a line that is perpendicular to the y -axis.
Answer to Problem 27P
The slope of a line that is perpendicular to the y -axis is 0.
Explanation of Solution
Given information:
The slope of a line that is perpendicular to the y -axis.
The slope of x -axis is 0 and the x - and y -axis are perpendicular to one another on a graph. That means, any line that is perpendicular to y -axis must be parallel to the x -axis.
Conclusion:
Therefore, the slope of a line that is perpendicular to the y -axis is 0.
