vertex (2,-5), focus (0,7), directrix at y = -2
vertex (-2,5), focus (2, -2), directrix at y = 3
vertex (-2,-5), focus (0, 2), directrix at y = 2
vertex (2,5), focus (2,7), directrix at y = 3

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
