How do I read a line chart?

Reading a line chart involves looking at the x-axis and y-axis to understand the data trends over time.

What do the different lines represent?

Each line typically represents a different data series, showing how each one changes over the same time period.

How can I tell if the trend is increasing or decreasing?

You can tell by observing the slope of the line; if it goes up from left to right, it's increasing, and if it goes down, it's decreasing.

What if there are multiple lines on the chart?

You can compare the lines to see how different data sets relate to each other, noting which ones rise or fall together.
