The line is x=0 otherwise known as the y-axis.
The y-axis or x = 0.
It can have as many lines of symmetry as it has points.
The equation does not have and y variable in it: it is of the form x = c. Alternatively, the x coordinates of both points are the same and the y coordinates are not.
A circle has infinitely many points of symmetry. Every straight line that passes through the center of a circle is a line of symmetry.
The x-coordinate of the midpoint is the average of the x-coordinates of the end-points of the line and the y-coordinate of the midpoint is the average of the y-coordinates of the end-points of the line.
There could be many answers to this. If were thinking in terms of geometry: a triangle has between 1 and 3 lines of symmetry a square will always have 4 lines of symmetry. Irregular shapes might have a single line of symmetry. For instance, a building may have a single line of symmetry. a line between two points may only have one line of symmetry. because it is only 2 dimensions, it is impossible for it to have more than one line of symmetry.

Y Equals X PointsAll points that has the same y coordinates as x coordinates are on the y=x line.

The distance between any two points on a number line is the absolute value of the difference of the coordinates.
No.
It is the fact that their coordinates are not the same.
If the question refers to a single completely geometrically straight line of finite length in a plane, then a straight line will have two lines of symmetry. One symmetry line is perpendicular to the line being discussed and one symmetry line coincides with the line being discussed. The symmetry operation here is the one where every point of the figure is flipped perpendicularly across the symmetry line and the object is symmetric if that flipping produced exactly the same set of points. (Said differently, if flipping the set of points through a line produced an exact replica of the original set of points, then the like determining the flip is a symmetry line.) One level of complication occurs if the straight line which is the subject of the symmetry question is an infinitely long straight line. In such a case one symmetry line still coincides with the actual line, but all lines that are perpendicular to the straight line will be lines of symmetry. Thus, an infinitely long straight line has no single point as its "middle" and has an infinitely many symmetry lines consisting of all possible lines perpendicular to the original line.

If you draw a line right down the middle of it are both sides symmetrical then yes it does have line symmetry. If it doesn't have symmetry then it doesn't. But usually if it's a regular star it has line symmetry.
They could be the coordinates of a straight line equation
