Data Sufficiency

Lines n and P on xy plane. Is slope of n less than that of p?
1.Intersect point (5;1)
2.The Y intercept of line n is greater than that of p

sorry dont have oa

imo c

equation of line 1

x/a1+y/b1=1 (a1 and b1 are intercepts of X and Y axis)

slope1=-b1/a1
splope 2 = -b2/a2

since both line 1 and line 2 pass thru (5,1) so

a1(1-b1)=-5b1

so slope of line 1 = -b1/a1 = (1-b1)/5

slope of line 2 = -b2/a2 = (1-b2)/5


now unless b1 and b2 are both positive intercepts (b1, b2 >0) of Y axis, I think we can not determine whether slope1 > slope 2

I used graphical approach and got C aswell
