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