A line graph would best show the growth of Joey's bean plant over time as it measures the height of the plant weekly for two months, tracking changes in a single variable (height) across multiple time periods. A line graph is appropriate for displaying changes in a continuous measurement variable (height) across discrete time intervals (weeks).
