Verified Answer :

they only have 1 common point

Answer:

one

Step-by-step explanation:

If we have two lines,

Then there are only three cases possible,

Lines are parallel, i.e. there is no solution of the system of equations of lines.

Lines are intersecting, i.e. there are one solution of the system of equations of lines.

Lines are coincides, i.e. there are infinitely many solution of the system of equations of lines.

If there is one solution that is mean there is only one point that satisfies both lines or we can say that lines have one point in common.
