If the vertices of a hyperbola be at $(-2, 0)$ and $(2, 0)$ and one of its foci be at $(-3, 0)$, then which one of the following points does not lie on this hyperbola ?

Let $S$ and ${S}^{'}$ be the foci of an ellipse and $B$ be any one of the extremities of its minor axis. If $\Delta {S}^{'}BS$ is a right angled triangle with right angle at $B$ and area $(\Delta {S}^{'}BS)=8\mathrm{sq}.\mathrm{units}$, then the length of a latus rectum of the ellipse is :

Suppose that the points $(h, k), (1, 2)$ and $(-3, 4)$ lie on the line ${L}_{1}.$ If a line ${L}_{2}$ passing through the points $(h, k)$ and $(4, 3)$ is perpendicular to ${L}_{1},$ then $\frac{k}{h}$ equals:

Let the equations of two sides of a triangle be $3x-2y+6=0$ and $4x+5y-20=0.$ If the orthocenter of this triangle is at $(1, 1)$ then the equation of it's third side is:

If a hyperbola has length of its conjugate axis equal to 5 and the distance between its foci is 13 , then the eccentricity of the hyperbola is:

A straight line $L$ at a distance of $4$ units from the origin makes positive intercepts on the coordinate axes and the perpendicular from the origin to this line makes an angle of $60^{\circ}$ with the line $x+y=0.$ Then an equation of the line $L$ is: Note: In actual JEE Main paper, two options were correct for this question. Hence, we have changed one option.

Two sides of a parallelogram are along the lines, $x+y=3$ and $x-y+3=0.$ If its diagonals intersect at $(2,4),$ then one of its vertex is:

Two sets $A$ and $B$ are as under: $A={(a, b)\in R\times R :|a-5|<1 \text{and} |b-5|<1};$ $B={(a, b)\in R\times R:4{(a-6)}^{2}+9{(b-5)}^{2}\leq 36}.$ Then :
