# If the four lines are extended, which system would have only one solution? 1. line a and line b 2. line b and line c 3. line b and line d 4. line c and line d  annan65

A line a and line b

Step-by-step explanation:

Lines b and c are parallel (no intersection points), so the system will have no solutions.

Lines b and d are parallel (no intersection points),  so the system will have no solutions.

Lines c and d coincide (infinitely many intersection points),  so the system will have infinitely many solutions.

Lines a and b will intersect after extension, so the system of these two equations will have only one solution.  ### Other questions on the subject: Mathematics Mathematics, 21.06.2019, macenzie26 Mathematics, 21.06.2019, emiller6462
