Given: Lines k and m are parallel to each other.
Let's jump straight to....
Statements 1 and 2 combined
There are many cases that satisfy BOTH statements. Here are two:
Case a:
In this case, the slope of line k is POSITIVE
Case b:
In this case, the slope of line k is NEGATIVE
Since we cannot answer the target question with certainty, the combined statements are NOT SUFFICIENT
Answer: E
