Understanding Linear Graphs and Their Properties

Algebra • Graphs

Key concepts

What you'll likely be quizzed about

  • Linear graphs depict relationships defined by linear equations, typically in the format y = mx + b.
  • Here, m represents the gradient, indicating the rate of change, and b signifies the y-intercept, or the point where the line crosses the y-axis.
  • Recognizing these elements is crucial for interpreting graphical data and making predictions.

Key notes

Important points to keep in mind

Gradient indicates the slope of a line.

The steeper the line, the greater the absolute value of the gradient.

Linear graphs can be used to model real-life situations.
