If the abscissa of a point m on the parabola y2 = 16x is 6, then the distance from m to the focus f is 0______ .
The Quasilinear equation of parabola y2 = 16x is: x = - 4 ∵ the distance from m to focus f is equal to the distance from m to Quasilinear, the abscissa of M is 6, and the distance from m to focus f is 6 + 4 = 10, so the answer is: 10
