Plot two straight lines to find the solution to a pair of simultaneous equations Which diagram shows the graphical solution to: \( \begin{array}{c}3 x+2 y=12 \\ y=3-x\end{array} \) ![A four quadrant plane. Y axis --3 to 6 and x axis -4 to 7. A blue line goes from bottom left to top right sloping upwards. It goes through (-3, 0) and (0, 3). A red line goes from top left to bottom right sloping downwards. It goes through (0, 6) and (4, 0) ]()
