Graphs going up (increasing) and down (decreasing)

1. Understanding Graph Trends

Graphs can show whether a quantity is increasing or decreasing over time.

• Increasing Graph:
  • The graph moves upward from left to right.
  • This indicates a rise in values.
• Decreasing Graph:
  • The graph moves downward from left to right.
  • This indicates a fall in values.

Tip: Always read graphs from left to right to determine trends.

2. Understanding Steepness (Slope)

The steepness of a graph tells us how fast values change.

• Steep slope (sharp incline or decline):
  • Shows a rapid increase or decrease.
• Gentle slope (gradual incline or decline):
  • Indicates a slow increase or decrease.

Tip: A steeper line means a quicker rate of change.

3. How to Analyse a Graph's Slope

1. Place your finger on the left side of the graph.
2. Move your finger to the right.

• If your finger moves up, the graph is increasing.
• If your finger moves down, the graph is decreasing.
