The graphs of ax + by = c, dx + ey = f will be
- 1parallel if the system has no solution
- 2coincident if the system has finite number of solutions
- 3intersecting if the system has only one solution.
Which of the above statements are correct?
Elementary MathematicsAlgebra
- A1 and 2 only
- B2 and 3 only
- C1 and 3 only
- D1, 2 and 3
Explanation
Parallel lines give no solution and intersecting lines give exactly one solution; coincident lines give infinitely many solutions, so statement 2 is wrong.
