Answer: A and E
Explanation:
The answer would only be E since all the others don't make sense.
Why it isn't B: The slope of a line can also be negative if the line drops from the left to right.
Why it isn't C: If two lines have the same slope, then that would mean that they are parallel.
Why it isn't D: Steep means to be sharply angles, basically perpendicular. For the line to go downhill and be steep, it will be positive.
Hope this helped :)
