parabola

if the vertex of a parabola is (4,9) what is the axis of symmetry x = 4

A parabola has a Vertex at (4,-2) and a Focus at (6,-2). Find the equation of the parabola and the lotus rectum. Equation of a parabola given the vertex and focus is: (x – h)^2 = 4p(y – k) The vertex (h, k) is 4, -2 The distance is p, and since the y coordinates of -2 are equal, the distance...
