WILL GIVE BRAINLIEST IF BOTH ARE CORRECT

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

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_|

A) direct variation; y = 8/x

B) direct variation; y = 8x

C) inverse variation; xy = 8

D) inverse variation; y/x = 8

Q1) D

Q2) C

Step-by-step explanation:

Q1)

y ∝ x

y = kx

Let x=-1,y=2

2 = k(-1)

k = -2

Q2)

directly (y=kx)

Let x=2,y=4

4 = k(2)

k = 2

y = 2x

inverse (y = k/x)

Let x=2,y = 4

4 = k/2

k = 8

xy = 8
