MCQ
A system of two linear equations in two variables has a unique solution if their graphs :
- ACoincide
- BCut the $x-$ axis
- CDo not intersect at any point
- ✓Intersect only at a point
✓
Answer
Correct option: D.
Intersect only at a point
The number of solutions of a system of two linear equations in two variables is equal to the number of common points between the graphs of given linear equations.
If a system has a unique solution then their graphs must intersect in only one point.
If a system has a unique solution then their graphs must intersect in only one point.
