# A triangular pyramid begins with these coordinates:

**Question description**

** **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.
