We need a point and a slope.
Since f(1) = 1, the point we want is (1,1). Since we found earlier that f'(1) = 2, 2 is the slope we want.
We want a line of the form
y = mx + b whose slope is 2, so m = 2: y = 2x + b.
We also want (1,1) to be on the line, so
1 = 2(1) + b.

Klein bottle
In mathematics, the Klein bottle // is an example of a non-orientable surface; informally, it is a surface (a two-dimensional manifold) in which notions of left and right cannot be consistently
defined. Other related non-orientable objects include the Möbius strip and the real projective plane.

Let $V^k\subset \mathbb C^n$ be a sub variety, such that all its irreducible components have dimension $\ge k$. Is it true that $\mathbb C^n\setminus V^k$ has homotopy type of a CW complex of
