The Geemer and Samus both need to be in a position relative to the slope where the initial damage boost will allow Samus to land on the slope and perform a slopespark. A normalized setup can be achieved by entering from the right door, shinecharging down the slope and stopping before the Geemer is on screen (just before the second mushroom). Once shinecharged, walk left down the slope to bring the Geemer on screen and perform the slopespark by damage boosting off it.
