In $Fig.,$ the point identified by the coordinates $(-5,3)$ is

If $(2 a+5,3 b+2)$ and $(a+11, b+14)$ are coordinate of the same point, then the value of $a$ and $b$ are $\ldots \ldots . .$ respectively.

Plot the following points and check whether they are collinear or not:

$(1,1),(2,-3),(-1,-2)$

The line joining $P(5,3)$ and $Q(5,-8)$ intersects……….

The point at which the two coordinate axes meet is called the
