Question

graph the world population total for the past 50 years. which type of graph would you use?1. x y scatter2. line3. bar/column4. pie

Explanation:

To show changes in world population over 50 years, we need a graph that clearly displays trends over a continuous time period. Line graphs are ideal for tracking data changes over time, as they connect data points to visualize upward/downward trends.
