Find the equations to the straight lines which pass through the point (h, k) and are inclined at angle tan-1 m to the straight line y = mx + c.
Given: equation passes through (h, k) and make an angle of tan-1 m with the line y = mx + c
To find: equation of given line
We know that the equations of two lines passing through a point x1,y1 and making an angle α with the given line y = m’x + c are
m’ = m so,
x1 = h, y1 = k, α m’ = m.
So, the equations of the required lines are
and y = k
Hence, Equation of given line is and y = k
