Is the slope of Line 1 positive?

Statement #1: The angle between Line 1 and Line 2 is 40º.
Statement #2: Line 2 has a slope of 1.

I think is the answer is E
Stmt 1 - doesn't provide much insight
Stmt 2 - provides info on line 2 and nothing about line 1
Taken together, no insight about line 1

IMO C,

A - both slopes can be -ve or +ve or a mix of two
B - slope of line2=45 but no info on line1

both A & B
worst case: even if slope of line is less than 45 then it would be 45-40=5 deg. which is +ve
Premise: If you like my post
Conclusion : Press the Thanks Button ;)
