X and Y Intercepts

X and Y Intercepts. Intercept. In a function, an intercept is the point at which the graph of the line crosses an axis. If it crosses the y-axis it is called the Y INTERCEPT and has the point (0,Y) If it crosses the x- axis it is called the X INTERCEPT and has the point (X, 0).

  1. X and Y Intercepts

  2. Intercept • In a function, an intercept is the point at which the graph of the line crosses an axis. • If it crosses the y-axis it is called the Y INTERCEPT and has the point (0,Y) • If it crosses the x-axis it is called the X INTERCEPT and has the point (X, 0)

  3. Finding Intercepts on Graph

  4. From an Equation

  5. Example 3

  6. Example 4

  7. Summary • You should be able to find X and Y intercepts from: • Graph • Table • Equation You should know what the intercepts represent in a problem situation
