Question

Which of these best describes a line?

Answer 1

A line is parallel that connects opposite corners of a flat shape, I hope that this helps! <span />

Answer 2

The requirements of a line:
-totally straight (no curves)
-no thickness (we draw it with thickness but that's just so we can see it)
-extends infinitely in either direction (both ends go on forever)

whichever option is closest to that is your answer
