Question

7. When the graph of pair of linear equations intersect at a point, then the system of equations will have:
(a) unique solution (b) no solution (c) infinite number of solutions (d) four solutions​

Answer 1

Answer:

ANSWER

If the lines intersect at a point, then that point gives a unique solution of the given linear equations and pair of equations are consistent.

Answer 2

Answer:

The system of equations has one solution and it is (3,1)

Step-by-step explanation:

The Number of solutions of a set of linear equations can be found from the graph of the set of equations.

No solution

If the graph of he set of linear equations are parallel to each other, the the set of equations has no solution.

Infinitely many solutions

If the graph of the set of linear equations coincide, then the set of equations has infinitely many solutions.All points on the graph are solutions of the set of equations.

Unique solution

If the graph of the set of linear equations intersect at a point, then the set of equations has unique solution.The intersecting point is the solution of the set of equations.
