Find the equation of a straight line whose inclination is 60° and which passes through the point (0,-3,)
Answers
SOLUTION
TO DETERMINE
The equation of a straight line whose inclination is 60° and which passes through the point (0 , - 3)
EVALUATION
Here it is given that the inclination of the line is 60°
Slope of the line = m
= tan 60°
= √3
Now the given point is (0 , - 3)
Hence the required equation of the line is
y + 3 = √3 ( x - 0 )
⇒ y + 3 = √3x
⇒ √3x - y = 3
FINAL ANSWER
Hence the required equation of the line is
√3x - y = 3
