Which of the following pairs of linear equations are consistent/inconsistent? If consistent,obtain the solution graphically: $x-y=8, 3x-3y=16$.

(N/A) Given equations are $x-y=8$ and $3x-3y=16$.
Comparing with $a_1x + b_1y + c_1 = 0$ and $a_2x + b_2y + c_2 = 0$:
$a_1 = 1, b_1 = -1, c_1 = -8$
$a_2 = 3, b_2 = -3, c_2 = -16$
Calculating the ratios:
$\frac{a_1}{a_2} = \frac{1}{3}$
$\frac{b_1}{b_2} = \frac{-1}{-3} = \frac{1}{3}$
$\frac{c_1}{c_2} = \frac{-8}{-16} = \frac{1}{2}$
Since $\frac{a_1}{a_2} = \frac{b_1}{b_2} \neq \frac{c_1}{c_2}$,the lines represented by these equations are parallel to each other.
Therefore,there is no common point between the lines,which means the pair of linear equations is inconsistent.
