FAST FACTS ABOUT LINE GRAPHS

EVERY LINE GRAPH HAS:

• a title

• two sides (the vertical and horizontal axes)

• descriptive labels for each side (or axis)

• a scale calibrated to suit the data (by 1s, 2s, 5s, 10s, 25s, etc.)

FACTS:

Points on a line graph are connected by line segments.

A sloping segment indicates change; the steeper the slope, the greater the change.

From left to right, a rise indicates increase; a downward slope indicates decrease.

A horizontal (or flat) line segment indicates no change.
