2. gives the coordinates of points. if u plug them in 2x+3y=6 it doesnot equate. so not sufficient.

If r=3, s=2 does not satisfy the given equation 2x+3y=6 then doesnt it mean that data given by (2) is sufficient to say r=3, s=2 does NOT belong to region R?

Hence, B?


Fine, I got it, right B. i took the only one side which is silly,
yeh we can answer the question just with the second data

how do you define the region occupied by just 1 straight line...did you mean the region between the the line and X and Y axes? :roll:


fresinha12
in the xy plane, the region R consists of all points (x,y) such that 2x+3y=6. Is the point (r, s) in the region R

1) 3r + 2s=6
2) r=3, s=2

PLEASE show your working and not be like startupaddict who just posts answers..

I am curious to know what the answer is ..

I come up with D as the answer.. Region could mean the quadrants these lines go through

From equation one, you can figure out the slope = -2/3 writing it in the form of y = mx + b

Any equation with Negative slope, passes through quadrants I , II and IV

So sufficient, as it is in the region

when R and S points are given, they are in first quadrant.. so that is also sufficent..

What is the answer?
