By raising the pool a little to meet the grade on the upslope of the yard and building a sloping berm on the opposite side a retaining wall will become unnecessary.
Retaining wall above ground pool on slope.
On the down slope side you ll also have to build a retaining wall to keep the soil form shifting out from under the pool.
When retaining walls are built they slope slightly to one side in order to improve.
Even when your pool is 48 high there are conditions like a deck connected off the house that comes up to the pool where a safety fence will be needed.
Building a retaining wall to hold the slope is much safer if the slope runs more than 24 inches above the ground where the pool sits.

Use 3 4 minus gravel to help stabilize the soil under the pool then about 3 of sand between the pool and the gravel.

Save some of the sod that you remove when preparing the ground for the pool to cover the top of the backfill.
Wondering about the logistics around retaining walls to accompany your inground pool.
While a retaining wall is not needed to prevent runoff from entering the pool one is needed to support the high end of the slope.

Mark the perimeter of your wall with stakes and string for a straight wall.
A wall that leans into the soil it retains is less likely to be pushed outward by soil pressure than a plain old vertical wall.
In the photo above even though there was a significant drop off.
This can cause serious damage to the wall of your above ground pool and can even cause structural collapse.
