DSQ: Graphing an ordered pair - GMAT Quantitative Reasoning
Card 0 of 2
What quadrant contains the point 
, where 
?
Statement 1: 
Statement 2: 
What quadrant contains the point
Statement 1:
Statement 2:
Statement 1 alone tells you that 
and 
are of the same sign, so the point is in Quadrant I (both positive) or Quadrant III (both negative).
Statement 2 tells you that any of the following hold:
is positive and 
is negative - example: 
is negative and 
is negative - example: 
is positive and 
is positive - example: 
This places the point in any quadrant except Quadrant II (where 
is negative and 
is positive).
The two statements together only eliminate two quadrants and leave both Quadrant I and Quadrant III as possibilities.

Compare your answer with the correct one above
Graph the point 
.
I) 
is in quadrant IV.
II) 
.
Graph the point
I)
II)
Graph the point (a,b)
I) (a,b) is in quadrant 4
II)
To graph (a,b) we need to know a and b
I) Tells us which quadrant the point is in. In quadrant 4, the x value is positive and the y value must be negative.
II) Lets us find the following:
So the only possible location of 
is 
.
Therefore, both statements are needed to answer the question.
