Answer 1

From the table of number of rows and number of flowers is given.

To examine the relationship between the number of rows and flowers,

r is denoted as number of rows .

f is denoted as number of flowers.

From the first coordinate, the number of flowers is 4 times the number of rows.

Similarly in second coordinate, the number of flowers is 4 times the number of rows.

Example,

`f=4r`

Substitute the first coordinates to check.

`f=4*2`
`f=8.`

which satisfy the value of flowers.

Hence , the correct option is D which is,

`f=4r`
