WILL GIVE BRAINLIEST IF BOTH ARE CORRECT

These are two separate questions that have nothing to do with each other.



Find the constant of variation k for the direct variation.


X | f(x)

-1 | 2

0 | 0

2 | -4

5 | -10



A) k = –0.5


B) k = 2


C) k = –1.5


D) k = –2

Question 2


Does the data in the table represent a direct variation or an inverse variation? Write an equation to model the data in the table.


_x____|_2__|__4__|__8__|__12__|

_y____|_4__|_2___|__1__|__2/3_|



direct variation; y = 8/x

direct variation; y = 8x

inverse variation; xy = 8

inverse variation; y/x = 8
