Use the Distance Formula to write an equation of the parabola. A parabola and a directrix are graphed on a coordinate plane. The horizontal axis is labeled x and the vertical axis is labeled y. The parabola opens upward with vertex lying at ordered pair 0 comma 0 and focus F at ordered pair 0 comma 1. The parabola passes through the point labeled P with ordered pair x comma y. A line segment obtained by joining point F and point P. A directrix of equation y equals negative 1 is drawn parallel to x-axis. A point D with ordered pair x comma negative 1 lies on the directrix and joined with the point P. Line segment P D is perpendicular to the directrix. Point F and point P are joined to form line segment P F.

An equation of the parabola is $y=$
