Answer :

Given: (x1,y1) = A( – 1, – 3)

And tan θ = 1


To find:


The distance of a point from the line in the direction of the line.


Explanation:


So, the equation of the line passing through ( – 1, – 3) and having slope 1 is


Formula Used:



x – y = 2


Let x – y = 2 intersect the line 2x + y = 3 at point P.


Let AP = r


Then, the coordinate of P is given by



x and y


Thus, the coordinate of P is


Clearly, P lies on the line 2x + y = 3




3r


r


Hence, the distance of the point ( – 1, – 3) from the line 2x + y = 3 is
