Question

18) If a pair of linear equation is consistent, then the lines will be . .
A) parallel B) always coincident
c) intersisting or coincident D) always intersecting​

Answer 1

Answer:

The Part C is the correct solution.

Step-by-step explanation:

The system of two linear equations is consistent in following two cases

Case 1

When the lines are coincident then their are infinite many solutions and the system is consistent

Case 2

When the lines are intersecting then the system has unique solution and system is consistent

Thus

The Part C is the correct solution.

That is the lines are intersecting or coincident

Answer 2

Answer:

option C : interesting or coincident
