grexam just joined TestMagic.
1) y=ax+b
the line equation is ax-y+c=0
slope of an eauation in the form of ax+by+c=0 is -(b/a)
here given that xintercept is a =2(y intercept) i.e
a=2(-1)
a=-2
therefore slope=-(-1/-2)=-1/2
hence col B is greater

2)I think answer is C
please check again as its mentioned to be B am sure about this problem


please correct if wrong
