# Let's do it once again

Geometry Level 4

Let the equation $$x^{3} + y^{3}+ 3xy = 1$$ represents the coordinate of one vertex $$A$$ and the equation of a side $$BC$$ of the triangle $$ABC$$. If $$B$$ is the orthocenter of the triangle $$ABC$$, then the equation of side $$AB$$ is $$y = mx + c$$. Then find the absolute value of $$4-m - c$$.
