There are two bisectors of the coordinate axes.
Their inclinations with the positive x-axis are 45° and 135°
The slope of the bisector is m = tan 45° or m = tan 135°
i.e., m = 1 or m = -1, c = 0
By using the formula, y = mx + c
Now, substitute the values of m and c, we get
y = x + 0
x – y = 0 or y = -x + 0
x + y = 0
The equation of the bisector is x ± y = 0
