Match the steps to find the equation of the parabola with focus (-1, -8.75) and directrix y = -9.25. 1.
( *+1 ) + y +8.75 ) = ( y +9.25 )
x2 + 2x + 1 = 2y +9
Set the distance from focus to the
point equal to the distance from directrix
to the point.
Write the equation of the parabola.
2. ( X+1 + y +8 75 )
Find the distance from the point on
3. Use (x, y).
the parabola to the directrix.
4. y=
1
.X² +X-4
2
Square both sides and simplify.
=
y +9.25)
Choose a point on the parabola.
5. v( x+1 ) + y +8.75 »
6. vy+9.25 )
Find the distance from the focus to
the point on the parabola.
