You could come up with values of r,s to find out if it is on the line. But either way the equation is sufficient to determine if the point is on the line... I was trying to practice saving some time on computing the solution.. Or maybe just lazy

Given line :

2x+3y= 6

S1: 2r+3s = 6

If r=0, s = 2, (0,2) on the line.

This is sufficient to determine if point is on the line.

S2: r = 3, s = 2

Sufficient.

Answer: D

Do you mean to say that (r,s) is on the line? I too think D is the answer, but my calculations say that the point is not on the line.

This is a bizarre question because each statement gives sufficient, but conflicting answers. Going with D, but donâ€™t think such a question would ever come on the actual GMAT.

The equation is actually the one of the line (L) represented by y=-2*x/3+2

Statement (1) : 3r+2s=6

This is actually another line (K) such as y = -3*x/2 + 3

As we can see, The slops of (L) and (K) are not equal. Thus, the 2 lines intersect at 1 point only. Hence, we can have the point (r,s) on (L) or not on (L).

INSUFF

Statement (2) : r = 3 and s= 2
This gives us enough information to conclude without calculating. These values have to verify the equation of the line (L).

I think there is some thing wrong with the question here. when we talk about a region shouldn't the equation be something like this
2x+3y>=6 or 2x+3y<=6 or 2x+3y<6 etc

2x+3y=6 is straight line and it cannot represent a region. Positive can you check the question again ?

If thats the case the answer could be E . What do you guys think ?
