Understanding Line Graphs: A line graph connects data points with line segments to show trends over time, such as temperature changes throughout the day.

Drawing a Line Graph: Label the x-axis (usually time) and y-axis (the measured variable), scale both axes, plot the points, and connect them with line segments. Add a title to describe the data.

Curve Graphs: A curve graph connects data points with a smooth curve, useful for showing gradual changes or non-linear relationships, like plant growth over time or running speed over age.
