Check whether the following system of equations is consistent or not. If consistent, solve graphically x-2 y+4=0,2 x-y-4=0

\[\begin{aligned} & \frac{a_{1}}{a_{2}}=\frac{1}{2} ; \frac{b_{1}}{b_{2}}=\frac{-2}{-1}=2 \\ & \frac{a_{1}}{a_{2}} \neq \frac{b_{1}}{b_{2}} \end{aligned} \] Correct graph Solution is \(\displaystyle (4,4)\) or \(\displaystyle x=4\) and \(\displaystyle \mathrm{y}=4\)
