Write the equation of a parabola with focus of (1,-2) and vertex at (9,-2).
1 answer:
Because the y-coordinates are the same in this parabola, it is a sideways-opening parabola, or one of the form 
where p is the distance between the focus and the vertex. Our distance is 9-1 = 8, and the (h, k) of our vertex is (9, -2), therefore, the equation is 
. Not sure how much you need to simplify this, but that's the standard form.
