A triangular pyramid begins with these coordinates:

 A triangular pyramid begins with these coordinates:

P: (0, 5, 4)

Y: (–2, 7, 4)

R: (0, 7, 4)

A: (0, 7, 6)

The pyramid is then reflected over the xz-plane. The reflected image is then translated 3 units back, 2 units left, and 4 units up.Determine the coordinates of that final image, following these steps:

·  Write the general rule you use for the reflection.

·  Show the results of your calculations for the reflection.

·  Write the general rule you use for the translation. (Hint: Begin with the result of the rule for the reflection.)

·  Show the results of your calculations for the translation.
