Answer 1

@welshfella

Answer 2

can you eliminate any of the options?

Answer 3

I think its that last graph but I'm not for sure.

Answer 4

why do you think its the last one?

Answer 5

I've done the test before, I'm just not very good with graphs. I failed the test and am repeating it. I just came here to see if my answer was correct before submitting i, so I don't fail again.

Answer 6

here is a hint:

if a graph slopes downward, it means that the quantity under consideration is decreasing

Answer 7

if its raining all day, is the amount of water increasing or decreasing ?

Answer 8

Increasing.

Answer 9

yes :)
so any graph with a portion of it sloping downward can be eliminated
follow so far?

Answer 10

look at the last graph

Answer 11

the parts that i have marked in black slope downward

Answer 12

Okay so it couldn't be the one I was saying it was because the way it is it goes downwards..

Answer 13

yes :)

Answer 14

now the next hint

a graph with a horizontal line represents that the amount of quantity under consideration is neither increasing or decreasing.

Answer 15

so can the graph for rain water be a horizontal line?

Answer 16

No.. Because wouldn't that mean what you just said? It would be neither increasing or decreasing?

Answer 17

yes! :)

so you can eliminate any options that have a perfectly horizontal portion.

so which ones can you eliminate?

Answer 18

the second, the third, and the fourth graphs since the second one is going downward, the third one is increasing nor decreasing, and the fourth one is going downward. Leaving only the one that looks kind of like a set of steps to choose from.

Answer 19

is the second one downward?

imagine a car that goes from left to right. is it going up or down?

Answer 20

left to right

Answer 21

Up... I never thought about that one like that.
