Most relations that you have studied in mathematics have been linear. However, many non-linear also exist in real life.

### Right Bisector of a Two Lines

In this section, we will learn how to create an equation that represents the right bisector. A right bisector is a line that passes through the midpoint of a line at 90 degrees; it is sometimes called a perpendicular bisector. Given that it is a line, all lines can be represented in form:

y = mx + b

Where m represents the slope, and b represents the y-coordinate of the y-intercept.

Since the right bisector is at 90 degrees, in other words perpendicular to the line, you may need to touch up on a subject that you look at in Grade 9. Any line that is perpendicular to another has a slope that is the negative reciprocal of the other. So, if you have a slope m=3/2, the negative reciprocal of 3/2 is –2/3. This is explained in the video below.
