Question

16. Give an example of a linear equation that is perpendicular to y = 5

Answer 1

x = 1 is an example of a line that is perpendicular to y = 5.

Explanation:

The equation y = 5 is a horizontal line where all points on that line have a y-coordinate of 5. A vertical line is perpendicular to a horizontal line.

So, we can choose all the vertical lines, such as x = 1, x =2, and x = -5.
