For the first table:
The equation y = 3x represents the given table, as for each x value, y is three times the value of x.
The equation y = 3/2x also represents the given table, as for each x value, y is three-halves the value of x.
For the second table:
The equation y = 1/3x represents the given table, as for each x value, y is one-third the value of x.
The equation y = 3x does not represent the given table, as the values of y are not three times the values of x.
The equation y = 3/2x does not represent the given table, as the values of y are not three-halves the values of x.
Therefore, the only equation that represents the given table is y = 1/3x.
