The sign for infinity is ∞
A number line stretches out for infinity. So, infinity.

It seems you are referring to the Bible. The first line of the Book of John is "In the beginning was the Word, and the Word was with God, and the Word was God."
The set of points on a straight curve that extends to infinity in both directions is a line. A ray is the set of points that lie on a straight curve that is terminated at a point, and continues to infinity. It is also called a half-line. If the set is terminated at a point at both ends, then it is a line segment.
No.Unless the slope is zero, every line will extend from minus infinity to plus infinity. So part of it will be negative and part positive.No.Unless the slope is zero, every line will extend from minus infinity to plus infinity.

The number line is simply a line (never-ending) that contains all the numbers from negative infinity (on the left) to infinity (on the right).
line: it goes on for infinity. <---------> line segment: has 2 endpoints, does not continue. -------- ray: starts at one point, then goes on for infinity. --------->
Infinity
A story about a performer
A vertical line has a slope of infinity.
No. A half line (also called a ray) is a linear object which starts at the first point, and extends to infinity through the second point. So the half-line (or ray) AB starts at point A, and shoots 'through' B and continues past B to infinity. The half-line BA is the other way around: it starts at point B, and then shoots 'through' A and continues past A to infinity. These two half-lines/rays end up extending to infinity in opposite directions, so they are not the same (not congruent).
