Write the standard form of the equation of the parabola with its vertex at (0,0) and directrix x=2
***
given parabola opens leftward
its basic form of equation: (y-k)^2=-4p(x-h), (h,k)=coordinates of the vertex
for given parabola:
vertex(0, 0)
axis of symmetry: y=0 or x-axis
p=2 (distance from vertex to directrix on the axis of symmetry)
4p=8
equation: y^2=-8x
