To describe the difference between line K and line L, we would need specific information about their positions on the coordinate plane. However, based on your request, it seems that line K is positioned lower on the y-axis compared to line L.
If line K has been moved up by a certain number of units on the y-axis to become line L, please specify how many units. For example:
"Line K has been moved up 3 units on the y-axis to become line L."
Please provide the specific number of units if you have that information!
