Answer -
There are two bisectorsof the coordinate axes.
Their inclinationswith the positive x-axis are 45o and 135o
The slope of thebisector is m = tan 45o or m = tan 135o
i.e., m = 1 or m = -1,c = 0
By using the formula,y = mx + c
Now, substitute thevalues of m and c, we get
y = x + 0
x – y = 0 or y = -x +0
x + y = 0
∴ The equation of thebisector is x ± y = 0
