Q. 254.0( 6 Votes )
Two lines passing through the point (2, 3) intersects each other at an angle of 60o. If slope of one line is 2, find equation of the other line.
Answer :
Let the slope of the first line be m1
Given, m1 = 2
Let the slope of the other line be m2.
Angle between the two lines is 60°.
⇒ 
Case 1: When 
The equation of the line passing through point (2, 3) and having a slope m2 is
⇒ 
∴ Equation of the other line is 
Case 2: When 
The equation of the line passing through point (2, 3) and having a slope m2 is
Equation of the other line is
