What to Focus On

  • Variables x and y are used in linear equations.
  • The variable written as the subject is the dependent variable.
  • The other variable is the independent variable.

  • An ordered pair has two numbers in a fixed order.
  • The first number is the first component and the second is the second component.
  • Order matters in ordered pairs.

  • The cartesian plane has two perpendicular number lines.
  • The horizontal line is the x-axis.
  • The vertical line is the y-axis.

Common Mistakes to Avoid

The first number in an ordered pair can be swapped without changing the point.

A point on the x-axis has y as its first component, and a point on the y-axis has x as its second component.

The x-axis has slope undefined and the y-axis has slope 0.
