Dear Sir Why are we assuming that greater than or lesser than symbol is deemed to be “equals” symbol in finding the coordinates for constraints
John Moffat says

Because the line that we draw when it is equals is the boundary. If it is a less than constraint then any values of the two variables must be either on the line (i.e. equals the constraint) or below the line (i.e. less than the constraint).
I do explain this in the lectures.

Thanks Mr John and good morning. It is possible to do the inverse of the x and y axes for standard and executive chairs and still arrive at the same optimal production plan? Here S is positioned on the vertical axis while E on the horizontal axis.

It does not matter which axis you use for each product – the answer will be the same (even though the lines will look different).
However, do appreciate that you cannot be asked in the exam to draw the graph – but what can happen is that the graph might be already drawn for you in the question, and you can be tested that you understand it.

Okay Sir. Thanks
