Find the equation of the straight line passing through (3, – 2) and making an angle of 60° with the positive direction of y – axis.

Answer :

A line which is passing through (3, – 2), the angle is 60o with the positive direction of the y – axis.

To Find: The equation of a straight line.


Formula used: The equation of line is [y – y1 = m(x – x1)]


Explanation: Here, angle, θ = 60o with the y – axis. So, it makes 300 with the positive direction of the x – axis.


SO, The slope of the line, m = tan θ


m = tan 30o


m =


The line passing through (x1,y1) = (3, – 2)


The required equation of line is y – y1 = m(x – x1)


y – ( – 2) = (x – 3)




Hence, The equation of the line is
