It is generally delightful to create a set up where the children investigate and reach conclusions! A lot of skills come into picture - deductive logic, pattern reading, group work and self learning. One such investigation was to be able to read slope and intercept from y=mx+c. I started with giving students a lot of equations and randomly plot them on a graph - single grid. Then I discussed rise and run with them. Followed the following investigation table:

ANALYSES - What do I deduce from the information in the table? What do you notice?

Equation | Rise ÷ Run | Where the line cuts y-axis | |

1 | |||

2 | |||

3 | |||

4 | |||

5 |

**CHECK YOUR UNDERSTANDING -**

*For each of the following, write the slope ’m’ and intercept ‘c’ from the equation y = mx + c*EQUATION | Slope and Intercept |

1. Y = 5x – 7 | |

2. Y = 6 | |

3. Y = -3x + 5 | |

4. Y = -2x – 9 | |

5. Y = 7x |

Quite a stormy class it was with students struggling and feeling insecure. But finally, we reached there...

Wow! I was a facilitator!
