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.

Test that the marking algorithm works
Check that the marking algorithm works with different sets of variables and student answers using the interface below.
Create unit tests to save expected results and to document how the algorithm should work.
There's an error which means the marking algorithm can't run:

No unit tests have been defined. Enter an answer above, select one or more notes, and click the "Create a unit test" button.
The following tests check that the question is behaving as desired.

This test is not currently producing the expected result. Fix the marking algorithm to produce the expected results detailed below or, if this test is out of date, update the test to accept the current values.
One or more notes in this test are no longer defined. If these notes are no longer needed, you should delete this test.

When you need to change the way this part works beyond the available options, you can write JavaScript code to be executed at the times described below.
To account for errors made by the student in earlier calculations, replace question variables with answers to earlier parts.
In order to create a variable replacement, you must define at least one variable and one other part.
| Variable | Answer to use | Must be answered? | |
|---|---|---|---|
The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:
These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
