The equation of a line parallel to the line ax+by+c=0 is ax+by+k=0.
Thus, the equation of a line parallel to 4x−3y+2=0 is 4x−3y+c=0.
The distance of a line ax+by+c=0 from origin is a2+b2+c2∣c∣.
Given the line 4x−3y+c=0 is at a distance of 53 units from origin
⇒16+9∣c∣=53
⇒5∣c∣=53
⇒c=±3.
Hence, the equation of the lines are 4x−3y+3=0 and 4x−3y−3=0.
Clearly point (−41,32) satisfy the given equation 4x−3y+3=0.
