Answer :

Given: (x1,y1) = A(2, 3), θ = 45°

To find:


Distance of point from line.


Explanation:


So, the equation of the line is


Formula Used:




x – y + 1 = 0


Let PQ = r


Then, the coordinate of Q are given by



x, y


The coordinate of point Q is


Clearly, Q lies on the line 2x – 3y + 9 = 0




r = 4√2


Hence, the distance of the point from the given line is 4√2.
