Help and explain how

Answer 1

Answer:

Table shows a direct variation.

Step-by-step explanation:

For the direct variation equation representing the table will be in the form of,

y = kx

Where 'k' is the proportionality constant.

From the table attached,

For x = -10 and y = -20,

-20 = k(-10)

k = 2

For x = 1 and y = 2

2 = k(1)

k = 2

For x = 2 and y = 4,

4 = 2k

k = 2

For all points given in the table 'k' is same or constant.

Therefore, relation represented by the table shows a direct variation.
