Trajectories of points equidistant from two straight lines 3x + 4Y + 5 = 0,4x-3y-7 = 0

Trajectories of points equidistant from two straight lines 3x + 4Y + 5 = 0,4x-3y-7 = 0

If the distance between a point (x, y) and two straight lines 3x + 4Y + 5 = 0 and 4x-3y-7 = 0 is equal, the distance formula from a point to a straight line is obtained
|3x+4y+5|/√(3^2+4^2)=|4x-3y-7|/√(4^2+3^2)
3x+4y+5=±( 4x-3y-7)
The trajectory is two lines
x-7y-12=0
7x+y-2=0
