In the xy plane, does the point (a, b) lie above the line y=x?
(1) a=2
(2) b=a+2
(1) a=2
(2) b=a+2

In the xy plane, does the point (a, b) lie above the line y=x?
Each point of line y=x has the same x and y coordinates: (-7, -7), (1, 1), (100, 100), ...
(1) a=2. Not sufficient since no info about b
(2) b=a+2 --> since y coordinate of the point is 2 more than its x coordinate than it will lie above the line x=y, consider point (1, 3). Sufficient.

(1) a=2
(2) b=a+2
(1) a=2
(2) b=a+2
used substitution method
given that y = x
1) a=2, no mention of b
so the point (a,b) can fall either below the line or above the line y=x
so NS .. hence Options A & D are gone.
2) b = a+2
so take any value a, b will be greater than a by 2...
hence this point will always be above the line... Hence B....
