You can figure it out by looking to see if it's negative or not

Answer 12

yes

Answer 13

its negative.

Answer 14

\[\huge \frac{{\Delta y}}{{\Delta x}} < 0\]

Answer 17

ok ... so its linear increases?

Answer 18

Do you really think it's increasing?

Answer 19

well if its not decreasing then it has to be increasing..

Answer 20
