Manipulative 1 - Intercept Created with GeoGebra.

An intercept is a point where a graph intersects (crosses) an axis. A x-intercept is a point where a graph intersects the x-axis. A y-intercept is a point where a graph intersects the y-axis. A z-intercept is a point where a graph intersects the z-axis.

Manipulative 1 shows the x-intercepts of a graph. Manipulative 2 shows the y-intercepts of a graph. Click on the blue curves in the manipulatives and drag them to change the figure. Note that the intercepts change as the graph changes.

Manipulative 2 - Y-Intercept Created with GeoGebra.
