what do you think the answer is

AZ · Answer

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"|dw:1616004048826:dw|

sxdsouls · Answer

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

AZ · Answer

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?

sxdsouls · Answer

yes

AZ · Answer

so

slope = rise / run

slope = -310/155

slope = ??

sxdsouls · Answer

-2
