\(y=mx+b\) is a straight line and its intercept is \(a\)

then

a)ab>0

b)ab<0

c)ab=0

Please try and post the complete questions. The question seems to be poorly worded for a GRE question.

Intercept \(a\) is with respect to which axis.

For example if it is Y axis. Then \(a=b\). Then \(ab = b^2 > 0\)

Also please follow the rules of posting.
