(A) pair of linear equations is said to be consistent if it has at least one solution.$1$. If the lines intersect at a single point,the system has a unique solution,and the condition is $\frac{a_1}{a_2} 
eq \frac{b_1}{b_2}$.$2$. If the lines are coincident,the system has infinitely many solutions,and the condition is $\frac{a_1}{a_2} = \frac{b_1}{b_2} = \frac{c_1}{c_2}$.Since both cases provide at least one solution,the lines are either intersecting or coincident.

If a pair of linear equations is consistent,then the lines will be
