You're on the right track, but that's a rather imprecise ... not to say 'sloppy' ... way to say it. The "value" of a point on the line is a meaningless concept. And averaging two points gives only the location of the point midway between those two points. The 'x' coordinate of the midpoint of a line segment is the average of the 'x' coordinates of its ends. The 'y' coordinate of the midpoint of a line segment is the average of the 'y' coordinates of its ends.

Yes. Real numbers are points along a continuous infinite number line with its midpoint at 0.
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.
-- The x-coordinate of the midpoint is the average of the x-coordinates of the end-points. -- The y-coordinate of the midpoint is the average of the y-coordinates of the end-points. -- The average of two numbers is 1/2 of (the first number plus the second number).
The 'x' coordinate of B is the average of the 'x' coordinates of A and C. The 'y' coordinate of B is the average of the 'y' coordinates of A and C.

The 'x' coordinate of the midpoint is the average of the 'x' coordinates of the segment's ends. The 'y' coordinate of the midpoint is the average of the 'y' coordinates of the segment's ends.

The coordinates of the midpoint are the averages of the coordinates of the end points. So (0, 7.5).
The coordinates of the midpoint are the averages of the coordinates of the end points. So (0, 7.5).
You can't find the midpoint of a general line as a general line is infinitely long. However you can find the midpoint of a Pacific line between two points add up the x values divide by 2. Add up the y values divide by 2. That is the coordinate of the midpoint of a Pacific line.
On a number line, that would be a single number that describes the position - basically, the number itself.
well, a line consists of an infinite number of points the three important points on a line are start (the origin of the line) end (the end of the line) midpoint (halfway across the line)
