Answer:
In analytic geometry, a point indicates a location on the coordinate plane through (x,y) coordinates.
On the other had, a point doesn't have dimension, that is, it doesn't have length or with, it just indicates location.
Similarly, a line has length but no width, that is, a line can describe an specific length, that it, because a line can be defined as subsequent points one after another, forming only one dimension, the length.
The third option is not true, because a distance along a line is actually a segment, which has to have an initial point and an ending point.
At last, a plane does consist of an infinite set of points, this is absolutely true, because a plane extends to the infinite as line do.
Therefore, the right answer are first and last one.
