Answer :
Given: (x1,y1) = A(2, 5), tanθ
⇒ sin θ and cos θ
To find:
The distance of a point from the line parallel to another line.
Explanation:
So, the equation of the line passing through (2, 5) and having a slope is
Formula Used:
⇒
⇒ 3x – 4y + 14 = 0
Let 3x – 4y + 7 = 0 intersect the line 3x + y + 4 = 0 at point P.
Let AP = r
Then, the coordinate of P are given by
⇒ x and y
Thus, the coordinate of P is
Clearly, P lies on the line 3x + y + 4 = 0
⇒
⇒ 3r = – 15
⇒ r = – 5
Hence, the distance of the point (2, 5) from the line 3x + y + 4 = 0 is 5
