B)The quantity in Column B is greater.
C)The two quantities are equal.
D)The relationship cannot be determined from the information given.


Slope betwene (0,0) and (-6,-5)

We get 5/6

similarly between (0,0) and (a,b)

We get b/a

Since the points are on same lines, there slopes will be equal.

5/6 = b/a => 5a = 6b, from this we can say a > b.

A.
