1) First step. Graph both linear equations to determine whether or not the bisector is acute or obtuse. You are going to have to determine it and it depends on the slopes of the linear equations. 2) Type in both directed distance formulas, as follows. 3) Simplify the denominators, rationalize the denominators as well.

4) Simplify the denominator

5) Simplify fractions

6) Distribute

7) Combine like terms



8) Group up like terms

9) Factor out the common terms, so the linear equation is in the form Ax+By+C = 0
