Answer :

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


Explanation:


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,



Here,
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
