if the value of a was -4, will answer choice b still be the answer? such that point a will be -4 and b equals -2 (ie -4+2). Am thinking the line will then be under the x=y line

Have a query, in the prompt it is mentioned that point lies above the line 'y=x', so only positive values of 'a' to be considered.? Because if negative values are considered then statement 2 won't be sufficient.

Re: In the xy plane does the point (a, b) lie above the line y=x [#permalink]
There is a very interesting concept that I have learnt.
Any point above the line x=y will have higher value of y as compared to x and any point below the line x=y will have lower value of y as compared to x so the question generally boiled down to if b>a and statement 2 proved it to be correct
IMO B
