Basic Algebra

The x and y-intercepts of a line is the point where the line intercepts, or crosses, either the x-axis or the y-axis

  • X-Intercept: when the line crosses the x-axis, the y value is 0
  • Y-Intercept: When the line crosses the y-axis, the x value is 0

Intercepts can be written in (x, y) form or as "the x-intercept is 2". It can't be written as x = 2 (this is an equation of a vertical line going through the point (2, 0).
