## Operations
A model of this concept must provide:
Kernel::FT | operator() (const Kernel::Line_2 &l, const Kernel::FT &x) const
| returns the \( y\)-coordinate of the point at `l` with given \( x\)-coordinate. More...

## Member Function Documentation

Kernel::FT Kernel::ComputeYAtX_2::operator() | ( | const Kernel::Line_2 & | l,
|  | const Kernel::FT & | x
| ) |  | const

returns the \( y\)-coordinate of the point at `l` with given \( x\)-coordinate.

Precondition
  `l` is not vertical.
