Question 160

Multiple Choice

Find the standard form of the equation of the parabola.
-Focus at (9,−5) ( 9 , - 5 ) , directrix y=−15y = - 15


A) (x−9) 2=20(y+5) ( x - 9 ) ^ { 2 } = 20 ( y + 5 )
B) (y+5) 2=20(x−9) ( y + 5 ) ^ { 2 } = 20 ( x - 9 )
C) (x−9) 2=20(y+10) ( x - 9 ) ^ { 2 } = 20 ( y + 10 )
D) (x+5) 2=20(y+10) ( x + 5 ) ^ { 2 } = 20 ( y + 10 )
