General Equation of Straight Line and Position of points w.r.t. line
Sir, in 3rd example of position of a point.... how are we able to determine that the line( 4x + 4y -3 =0) is below the line (x + y - 2=0).... because if positions of these lines are interchanged then i guess the inequalities will also change ( since, origin and the Point would lie on opposite sides w.r.t. (x+y-2 =0) and vice-versa for other line).... and then the answer would come out to be (R-{whatever the current answer is}).... Please clear this up.
