For example: Complete the table for the given rule: y = 2x

X | Y |

3 | |

2 | |

4 |

**Solution:**

For first missing value: y = 2(3) ⇒ y = 6

For second missing value: 2 = 2x ⇒ 1 = x

For third missing value: y = 2(4) ⇒ y = 8

Therefore, the table after completion is shown below:

X | Y |

3 | 6 |

1 | 2 |

4 | 8 |
