given point on a parabola is equal to the distance from that point to the focus. Latus Rectum The line segment is perpendicular to the axis of symmetry (and therefore parallel to the directory) which runs through the focus. Bounded by points (a,2a), (a, -2a), with a length of 4a. First General Equation of a Parabola y² = 4ax Where the vertex is at (0,0). Focus is located at (a,0). DirectX is represented by x = -a. The Axis of symmetry is the x-axis. Opens to the right. Second General ...
