A line intercepts x-axis at "a" and y-axis at "b". Is the slope of the line negative?

1) a^2 = b^2

2) a^3 = b^3

Why all you guys debate over the value "0" ?

Just try this way.

The question asked you whether the slope negative. Also it can assume that x=a and y=b Therefore, the slope can calculatyed on B/A

In statement I: if B positive, A Negative then slope is negative -- YES

if B positive, A positive then slope is positive -- NO

In statement II : it can infer from that equation and A and B

MUST have the same value. Thus, no matter how you calculate the slope is always be positive. So it is enough to answer this question which is NO.

In sum, I go for B surely. for those who doubt about the value of 0 I don't know what you are thinking of ?
