Answer 2

what do you think the answer is

Answer 3

remember

slope = rise over run

since we're going down from the peak, the rise will be a negative number

so how high up are you?
and how much do you "run"

Answer 4

she said 2 yeah yeah but 2 makes sense right- ._.

Answer 5

no

remember, we're going down so the rise is -310
and the run is 155

remember when I showed you negative slope and positive slope?

doesn't the image look like it has a negative slope?

Answer 6

yes

Answer 7

so

slope = rise / run

slope = -310/155

slope = ??

Answer 8

-2

Answer 9

there you go
