We can graphically represent a pair of linear equations as two lines. And lines may intersect, or may be parallel, or may coincide. ... Such a pair is called a dependent pair of linear equations in two variables. Thats why a dependent pair of linear equations is always consistent.

Ans.
An equation in x and y of 1st degree represents a straight line in 2D.
i) When the lines coincide or intersect each other, we can find a solution to the pair of equations.
Ex.
3x + 2y = 5
2x + 3y = 5
The solution is x = y = 1.
So the equations are consistent.
ii) When the lines are parallel, the pair of equations be inconsistent.
Ex.
x + y = 10
x + y = 5
They have no solution.
