I have swapped the $x$ and $y$ part b) of the advice so it says:

$X$ axis when the $y$ coordinate of the point is zero.

$Y$ axis when the $x$ coordinate of the point is zero.

Name the quadrants A,B,C,D instead of 1,2,3,4. Or could you give them compass coordinate NW,NE,SW,SE? Trying to keep two coordinate numbers in your head and then remember a number for the corresponding quadrant will tax some minds! It sounds silly but difficulty with holding numbers in your head is much more common than you'd think.

It looks like part a is always in the top-right quadrant, and similar for the next three parts. If you replace parts a to d with a "match choices with answers" part, you can shuffle the order of the choices, so that the answer isn't the same every time.

You could do the same with parts e to g.

The explanation at the top of the advice is very wordy and hard to follow. Here's my version:

You can think of a pair of coordinates as a directions to the desired point, starting from the origin.

The first part of the coordinates tells you how far to move along the horizontal $x$ -axis. Positive numbers are on the right and negative numbers are on the left.

The second part of the coordinates tells you how far to move along the vertical $y$ -axis. Positive numbers are above the origin and negative numbers are below.

For each part, something like "the first part is positive and the second part is negative, so the point lies in quadrant 3".

Lots of spelling mistakes - "coordiante", "axsis".

"All points on the x-axis correspond to a y value of 0, so we can assume that anything on the line y=0 is on the x-axis." is a little bit wrong. We don't assume anything. By definition, points with zero $y$ coordinate are on the $y$ axis.

For $(0,0)$ - your explanation is very long-winded. You can just say "the $x$ coordinate is 0 so it's on the $x$ -axis, and the $y$ coordinate is zero so it's also on the $y$ axis."

Check the order of the parts in the advice.

Advice

You can think of a pair of coordinates as a direction to the desired point, starting from the origin.

The first part of the coordinates tells you how far to move along the horizontal $\,x$ -axis. Positive numbers are on the right and negative numbers are on the left.

The second part of the coordinates tells you how far to move along the vertical $\,y$ -axis. Positive numbers are above the origin and negative numbers are below.

a)

The point lies in the:

$A$ quadrant when the first part is positive and the second part is also positive.

$B$ quadrant when the first part is negative and the second part is positive.

$C$ quadrant when the first part is negative and the second part is also negative.

$D$ quadrant when the first part is positive and the second part is negative.

b)

The point lies on the:

$X$ axis when the $y$ coordinate of the point is zero.

$Y$ axis when the $x$ coordinate of the point is zero.

Origin when both the $x$ and $y$ coordinates are zero.
