Hi Pretz,
This question is all about basic line and "slope" rules. You can solve it with some drawings.
Here's what you need to know to handle it. From the prompt, we know:
1) Line K has a NEGATIVE Y-intercept. That means that the line crosses the Y-axis BENEATH the Origin.
2) Line K has a NEGATIVE slope. That means the line goes "down and to the right"
The question asks which of the 3 options could be the X-intercept, meaning "which of these points on the X-axis COULD the line potentially cross?" At this point, you can plot each point and see if you can create a line that fits all of the given information.
By doing 3 quick sketches, you'll find that the first line has a negative slope, the second line has an infinite/undefined slope (the line goes straight up) and the third line has a positive slope (it goes "up and to the right").
Final Answer:
GMAT assassins aren't born, they're made,
