Question 48527
graph the parabola with focus (1,-1) and directix x=5

Draw coordinate x and y axes.
Plot the point (1,-1).
Draw the line x=5
The vertex is half-way between the focus and the directrix
or (3,-1)
"p" equals the distance from the focus to the vertex or "2".
The directrix is to the right of the focus so p=-2

The vertex form of the parabola is (x-h)^2=4p(y-k)
(x-3)^2=-8(y+1)
