Move along a line from left to right. If you rise as you move from left to rise, then the slope is positive. If you get lower as you move from left to right, then the slope is negative.

For statement 1, line could also have a positive slope and never pass through quadrant 2!

That's also true!

Shouldn't the answer be E as a negative slope can also move from III to IV or II to IV? similar to the first statement analysis.

If the slope is negative, then the line will (eventually) pass through 3 quadrants (one of which will be quadrant II)
