In class, I showed how to parametrize a plane using two parameters,
t and s. (They can have any value in the reals.) Present the
plane 7 x + 8 y  z = 10 as three equations x = ..., y = ..., and
z = ... in terms of the two parameters t and s. Prove that your
parametrization is correct.

Consider the plane x = t  s + 8, y =  2 t + 3 s 1, z = 4 s + 8.
Find the equation that describes this plane. Prove that your
equation is correct.
For one extra point on the homework, print out and use the homework
cover sheet. This is a *.pdf document that you print and staple to
the front of your homework.
