Mathematics Question on Vectors
The line 2x - y = 1 bisects the angle between two lines. If the equation of one line is y = x, then the equation of the other line is
A
7x - y - 6 = 0
B
x - 2y + 1 = 0
C
3x - 2y - 1 = 0
D
x - 7y + 6 = 0
Answer
x - 2y + 1 = 0
Explanation
Solution
Explanation:
Let the equation of the Other line bex−2y+1=0∴ Equation of bisecting the lines between two lines is2x−y−14+1=±x−2y+11+4⇒2x−y−1=±x−2y+1⇒x+y−2=0 and x=y
