If the two lines are actually "on top of each other", they can have infinitely many points in common. If they are parallel, they have no points in common. If they are perpendicular, they have one point in common.

How many common points for intersection of four lines?
- If you're working on a single sheet of paper (2-D), then you can draw four lines that intersect in 1, 2, 3, 4, 5, or 6 points. - If in 3-D space, then you can also draw four lines that don't intersect at all.
How many lines are determined by coplanar points a b c and d?
4*3/2 = 6 lines.
How many lines of symmerty of squre?
4, 2 diagonal through the corners, 2 through the mid points of the sides
How many straight lines can be formed by connecting any 2 of the 6 non-collinear points?
15 Consider one of the points. Call it point A. You can draw one line containing A through each of the other five lines (i.e., there are five lines that contain both A and another of the five points). Now, consider another of the points -- call it B. Excluiding the line that contains A and B, there are four lines that can be drawn containing B and one of the other four points. Continue this process for all the points. You get 5+4+3+2+1=15 lines. In general, if you have n non-collinear points, there are n+(n-1)+(n-2)+...+2+1=n*(n+1)/2 lines that can be drawn through any two of those points.
Which type of lines pass through points (-2 2) (2 2) and (-2 -2) (2 -2) on a grid?
They are opposite parallel lines with points of (-2, 2) (2, 2) and (-2, -2) (2, -2)
If you have 5 points how many lines go through atleast 2 of the points?

How many lines are determined by 13 points no 3 of which are collinear?
There are 13*12/2 = 78 lines.
How many lines can be drawn through 2 points?
1 straight line. An infinite number of curved lines.
How many lines are determined by coplanar points a b c and d?
4*3/2 = 6 lines.
If points A B and C all lie in a straight line but the other points are not on the line how many different lines can be drawn if each line contains at least two points?
2 lines, I believe.
How many points can you do with 10 lines?
The maximum is 10C2 = 10*9/(2*1) = 45
