There are two values of b which satisfies the above expression. b = 5 and b=1. Hence D is the right option.

I am lost in this one. I plug in the values of the points into the distance equation √(x1  x2)² + (y1  y2)2. And I obtained b = 1 and b=7. What I did wrong. Thanks for the help.

Can you show us your calculations? That said, the distance formula isn't really necessary here, since the two given points have the same ycoordinate. Cheers, Brent

I used the formula to try to calculate the distance and it did not work. I was trying to use the formula to practice with.
I used the formula SQUARE ROOT OF [(x1x2)² + (y1y2)²]
(x1,y1) = (b,2)
(x1,y1) = (2,2)
I got
3 = SQUARE ROOT OF (b+2)² 0 = b² + 4b + 4 3 0 = b² + 4b + 1
And I got stuck here.
I couldn't solve for b because it wouldn't solve. I was trying to do something like 0 = (b + ?)(b + ?), but nothing would fit it to get the coordinates that are the answer.
I'm not sure what I'm doing wrong?

A)The quantity in Column A is greater. B)The quantity in Column B is greater. C)The two quantities are equal. D)The relationship cannot be determined from the information given. hi Reetika, the points (b,2) and (2,2) should tell you that these are coordinates as shown Also since y coordinates are 2 in both cases, the points are in a straight line parallel to x axis. Now distance between the two points is 3 and this will totally depend on x coordinates.. so b(2)=3 two case.. b+2=3.....b+2=3.....b=1, so Column A>column B b+2=3.....b+2=3.....b=5, so Column A<column B D
