You can put this solution on YOUR website! Find the equation of the parabola satisfying the given conditions. The vertex of each is at the origin.
1. Directrix x = 20
parabola opens leftward
Basic equation: y^2=-4px
p=20
4p=80
Equation of given parabola: y^2=-20x
..
2. Directrix y = 2.3
parabola opens downward
Basic equation: x^2=-4py
p=2.3
4p=9.2
Equation of given parabola: x^2=-9.2y
