Question

How to find whether the point lies below or above the line x=y?

Answer 1

Hey Friend,

Let there be a point (x,y) and a line ax,by+c=0 on a Cartesian plane. Just put the values of point in the given equation and evaluate..

If ax+by+c>0 then the point is above the line

If ax+by+c<0 then the point is below the line

If ax+by+c=0 then the point is on the line
