the line drawn from the point ( 0,5) will form a right angled triangle with sides 13,5 and 12 ( that is at the point (12,0) on positive x axis). WE calculate the 12 by using Pyhtagoras theorem- 13^2 = 5^2 + 12^2.

Another line can be draw to intersect the point (-12,0) on the negative side.

Answer is points (12,0) and (-12,0)
