Does line L pass through Quadrant II?

(1) Line L has Positive X-Intercept

(2) Line L has negative Y-Intercept

For geometry Data Sufficiency problems (especially ones that don't have a picture already), sketch out your own picture. Your goal is to try to draw the picture in two different ways (that make the answer to the question different). If you can do that, the statement is insufficient!

Statement 1:

The light blue line doesn't go through quadrant II, while the dark blue line does. Not sufficient.

Statement 2:

The light purple line doesn't go through quadrant II, while the dark purple line does. Not sufficient.

Both statements together:

No matter how hard you try, you can't make the lines pass through quadrant II! Sufficient.
