 Manipulative 1  Intercept Created with GeoGebra. 

An intercept is a point where a graph
intersects (crosses) an
axis.
A xintercept is a point
where a graph intersects the xaxis. A yintercept
is a point where a graph intersects the yaxis. A
zintercept is a point where a graph intersects
the zaxis.
Manipulative 1 shows the xintercepts of a graph. Manipulative 2 shows the
yintercepts 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.
