Solve the following system of equations graphically : \[\begin{array}{r} 2 x-y-2=0 \\ -4 x+y+4=0 \end{array} \] Also, find the absolute difference between the ordinates of the points where given lines cut y - axis.
Marking-scheme solution
Solution is \(\displaystyle (1,0)\) or \(\displaystyle x=1, y=0\)
Absolute difference = $\displaystyle 2$ (consider - $\displaystyle 2$ also)
