On a graph paper, draw the lines x=3 and y=-5.
Now,on the same graph paper,draw the locus of the point which is equidistant from the given lines.
On the graph, draw axis XOX’ and YOY’
Draw a line l, x = 3 which is parallel to y-axis
And draw another line m, y = -5, which is parallel to x-axis
These two lines intersect each other at P.
Now draw the ∠ bisector p of angle P.
Since p is the ∠ bisector of P, any point on P is equidistant from l and m.
Therefore, this line p is equidistant from l and m
