Answer 1

No

Explanation:

If there is a direct variation then scale factor(k) is same

`\boxed{\sf k=(y)/(x)}`

• (0,0) Ignore it

Come to second point

• (2,4)

`\\ \rm\longmapsto k=(4)/(2)=2`

For third point

• (3,9)

`\\ \rm\longmapsto k=(9)/(3)=3`

Hence verified

Answer 2

• No

Explanation:

Direct variation is a function y = kx.

From the graph we have:

• x = 0 and y = 0, it gives k could be any value
• x = 2 and y = 4, it gives k = 2
• x = 3 and y = 9, it gives k = 3

As we see k is not same for different points of the graph so this is not a function y = kx hence no direct variation.
