" The point of the form (a,a),where a lies on "

The point of the form (a,-a), a!=0 lies on

The point of the form (a,a) always lies on

The point of the form (a,a) always lies on

The point of the form (a, a) always lies on :

The point of the form (a,-a) always lies on the line

The point of the form (a,-a) always lies on the line

The point of form (a, -a) always lies on the line

The point (x,0) where x lt 0 lies on .

If lim_(x rarr-a)(x^(7)+a^(7))/(x+a)=7, where a<0 then there exists at least one a for which point (a,2) where lies on the line
