Tell whether x and y show direct variation.Explain your reasoning.If so, find k #3

WINSTONCH [101]

Answer:

x and y do not show direct variation.

Step-by-step explanation:

The formula for direct variation is

y = kx Divide each side by y

k = y/x

k should have the same value for every point except, of course, (0,0)

For the first point,

k = 2/(-1) = -2

For the third point,

k = 2/1 = 2

The values of k are different, so x and y <em>do not</em> show direct variation.
