The point (a, b) is in Quadrant II.
x = a and y=b
x will always be -ve and y would be +ve
but
a+b may or may not be +ve as (-3,+5) ; a+b ; 2 or (-3,1) a+b ; -2
insufficient
#2
a − b > 0
only possible when a>b when b can be +ve or -ve
insufficeint
from 1 & 2
Bunuel could you please provide solution to this question , not able to understand the co relation between given graph and relation in stmnt 1 & 2
