Which axis passes through the point $\left(7 \frac{3}{4}, 0\right)?$

In the figure,the point identified by the coordinates $(-5, 3)$ is:

If the point $(a, 0)$ is on the ray $OX^{\prime}$,is $a$ a positive number or a negative number?

Plot the following points on a Cartesian plane and check whether they are collinear or not:
$(0,0), (2,2), (5,5)$

Plot the point $P(-6, 2)$ and from it draw $PM$ and $PN$ as perpendiculars to the $x$-axis and $y$-axis,respectively. Write the coordinates of the points $M$ and $N$.

The line joining $X(3, 5)$ and $Y(-4, 5)$ is parallel to the $\ldots \ldots \ldots$ axis.
