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 -15 to 30 and x axis -15 to 25. A blue line goes from bottom left to top right sloping upwards. It goes through (-10, -7) and (10, 12). A red line goes from bottom left to top right sloping upwards. It goes through (0, -6) and (10, 9) ]()
