Inside a space laboratory orbiting Earth, Emek and Luna examined a solar array that was producing unexpected amounts of power. The engineers had recorded energy output at different operating settings, but they needed to find the model that best matched the data. Emek and Luna plotted each measurement on a coordinate grid and compared several possible lines. They looked at how the power changed as the settings increased and identified the graph that followed the same linear pattern as the recorded points. After selecting the correct model, they shared the results with the engineers, who adjusted the solar array settings to produce energy more efficiently.
