Answer: E.



But if we combine statements 1 and 2, we can have only line passing through two points (one point in Q3 and the other in Q4). Is this not correct? how should the combination of statement 1 and 2 be interpreted?

STAT1 and STAT2 alone are not sufficient as the line can be any way so slope can be positive negative, zero or infinity

STAT1 and STAT2 together are also not sufficient as there can be two cases which will give both positive and negative slopes
(Figure attached)

So, answer will be E

Hope it helps!

Dear Bunuel,

Can you please explain in little detail how the red line and green line are respectively having negative and positive slope.

I cannot understand that.

Thank You in advance.

P.S.From now on I'll keep in mind and will post OA at the time of posting the question.

Thanks Bunuel. I checked the Book. It helped.

Learned about positive, negative, zero and un defined slope.
