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.
