Simplifying
(y + -1) * dx + (x + 1) * dy = 0

Reorder the terms:
(-1 + y) * dx + (x + 1) * dy = 0

Reorder the terms for easier multiplication:
dx(-1 + y) + (x + 1) * dy = 0
(-1 * dx + y * dx) + (x + 1) * dy = 0
(-1dx + dxy) + (x + 1) * dy = 0

Reorder the terms:
-1dx + dxy + (1 + x) * dy = 0

Reorder the terms for easier multiplication:
-1dx + dxy + dy(1 + x) = 0
-1dx + dxy + (1 * dy + x * dy) = 0

Reorder the terms:
-1dx + dxy + (dxy + 1dy) = 0
-1dx + dxy + (dxy + 1dy) = 0

Combine like terms: dxy + dxy = 2dxy
-1dx + 2dxy + 1dy = 0

Solving
-1dx + 2dxy + 1dy = 0
