11-68.

For each of the following equations, list every point where its *three-dimensional* graph intersects one of the coordinate axes. That is, what are the *-*,

*, and* -

*-intercepts? Express your answers in*

To find the intercept of a given axis, set all other variables to zero.

For example, the-intercept will be.

To find the-intercept, letandRepeat the process to find the

-intercept.. and
