Beyond the Answer
To determine if the solution \( (-0.5, 1.5) \) is correct, we need to substitute these values into both equations of the system. If both equations hold true when substituting \( x = -0.5 \) and \( y = 1.5 \), then the solution is indeed correct. Make sure to check each equation carefully, as sometimes, errors can occur in solving or graphing that can lead to concluding the wrong solution. It's also crucial to visually confirm where the lines intersect on the graph. Just because a student sees a point that looks like an intersection doesn't mean it's exact—the precision of the graphing or the rounding of values may lead to errors. Using exact calculations improves the chances of arriving at a true solution!
