$\"\"$

From the table,

Substitute the values of $\"\"$ in the direct variation equation $\"\"$ to find a.

$\"\"$

Divide each side by negative 3.

$\"\"$

The direct variation equation that relates x and y is $\"\"$ .

To check the equation, substitute the all values for x in the equation $\"\"$ to obtain random y - values of table.

If $\"\"$ then $\"\"$ .

Therefore the table does not represent direct variation. $\"\"$

The table does not represent direct variation.
