false
they intersect at a single point
This is False the correct definition is this: The number lines that form a Cartesian coordinate system are called the axes and the point where they intersect is called the origin.
False because they intersect at right angles.

false
Skew. * * * * * FALSE. In fact, if they are skew, they must intersect. They have to be parallel for them not to intersect.
False because they intersect at right angles.
In principle, yes an infinite number can be drawn, but in practise you would run out of graphite to draw the lines before getting to an infinite number. Even if you converted all the matter in the universe to graphite (using some Star Trekian style technology), you would still run out.

False Pi has infinite number of digits with no repetition so there is no way of discovering ALL of Pi's digits.
