It says that the point B satisfies the equation of which is a solution. That is, B is situated at the point with parameter .

Since BF is parallel to the y-axis, asking for the height of BF is simply asking for the y-coordinate of B (since F is on the x-axis).

Hence, the y-coordinate is given by .
