One more thing... points A and B should be labelled the other way round. Let's give your question the context of driving in a car: if you travel from A to B then, as it stands, the gradient is positive. Related to this, you do not give any indication where the equation for the gradient comes from. You could say something like, the gradient is the ratio of the vertical change ($y2-y1$) to the horizontal change ($x2-x1$).

Math.max()to set a minimum range displayed above the axis, e.g.
Math.max(yb+4,2)would set the 'y-max' to a minimum of 2.
You could use a similar method to check that the intercept is on the board (it currently isn't always).
Check your spelling, e.g. "coordiantes" and that your sentences read fluidly, e.g. "find the straight line equation of the line running through these points" can be written "find the equation of the straight line running through these points" and so on.

Error in variable testing condition
There's an error in the condition you specified in the Variable testing tab. Variable values can't be generated until it's fixed.

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:
These variables are available within the marking algorithm.
These values are available as extra variables in the marking algorithm.
These values are available as entries in the

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 Fix the marking algorithm to produce the expected results detailed below or, if this test is out of date, update the test to accept the current values.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.

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.
This part can't be reached by the student.
Add a "next part" reference to this part from another part.
None of the parts which can lead to this part are reachable either.
