At the shoreline
Yes, the continental slope drops downward to the edge of the continent at which point it plummets down for the depth of the continental plate. It depends upon whom you speak with, but a nation's boundary is generally considered 200 miles beyond that.
The world's combined continental slope is about 200,000 mi (300,000 km) long and descends at an average angle of about 4° from the edge of the continental shelf to the beginning of the ocean basins at depths of 330 - 10,500 ft (100 - 3,200 m). The slope is most gradual off stable coasts without major rivers and is steepest off coasts with young mountain ranges and narrow continental shelves. Slopes off mountainous coastlines and narrow shelves commonly have outcrops of rock. The dominant sediments of continental slopes are muds; there are smaller amounts of sediments of sand or gravel.
then the slope is x=y. there is no slope.

continental slope
The three parts of the continental margins are the Continental shelf, the Continental slope, and the Continental rise.
The continental shelf, continental slope, and continental rise combine to form the continental margin.

The continental shelf starts from the shore to a few miles out with less gradient of slope. The continental slope starts after shelf-break with a higher slope gradient, then follows the continental rise and abyssal-plain.
I'm text-based and cannot display images. However, you can easily find pictures of the continental slope by doing an image search on the internet. The continental slope is the steep slope that leads from the continental shelf to the deep ocean floor.
A sharp drop-off beyond the continental shelf is called a continental slope. The continental slope marks the transition between the continental shelf and the deep ocean floor.
A continental margin is NOT a part of a continent. It is the submerged outer edge of a continent that includes the continental shelf, continental slope, and continental rise.
continental margin
The continental shelf is a flattish area which extends from the shore out into the ocean and is made of continental crust. This ends in a slope (the continental slope) which descends to the abyssal plane, which is made of oceanic crust.
