Question

Draw the graph of the following pairs of lines on the same graph paper and hence check if they are parallel or not.
$3x+2y-8=0$
$3x+2y+12=0$
What can you conclude about the solution of the system of the simultaneous liner equations?

Answer 1

$3x+2y-8=03x+2y+12=0$

Here,

$\frac{a_1}{a_2}=\frac{b_1}{b_2}\ne \frac{c_1}{c_2}$

Parallel line system

No solution.
