Intersecting lines have exactly one point in common, which is the point of intersection. At this point, the two lines cross each other. If lines are parallel, they do not intersect and have no points in common. Lines that are coincident lie on top of each other and share infinitely many points.
there are 4 intersecting lines
To determine how many solutions a system has, we need to analyze the equations involved. Typically, a system of linear equations can have one solution (intersecting lines), infinitely many solutions (coincident lines), or no solution (parallel lines). If you provide the specific equations, I can give a more accurate assessment of the number of solutions.
There are 20 common points.
A minimum of two.
3 intersecting lines, because none of the three points are right angles.
They have an infinite number of solutions.
If the equations are linear, they may have no common solutions, one common solutions, or infinitely many solutions. Graphically, in the simplest case you have two straight lines; these can be parallel, intersect in a same point, or actually be the same line. If the equations are non-linear, they may have any amount of solutions. For example, two different intersecting ellipses may intersect in up to four points.
