Lesson Plan : Graphing equations

**Teacher Name: **
| Madame X |

**Grade:**
| Grade 9-10 |

**Subject:**
| Math |

**Topic: **
| Graphing linear equations using intercepts |

**Content: **
| Algebra
linear equations
x-intercept
y-intercept |

**Goals: **
| Students will identify linear equations and graph them using 2-3 coordinate points. |

**Objectives:**
| Students will be able to graph linear equations using the x and y intercepts. |

**Materials:**
| Overhead; overhead master |

**Introduction:**
| What is the x-intercept? y-intercept?
On a coordinate grid, identify x-axis, y-axis, then plot points: (5,0) and (0,4).
Define x-intercept: the coordinate at which a graph intersects the x-axis.
y-intercept: the coordinate at which a graph intersects the y-axis. |

**Development:**
| Given the equation 5x-4y= -20
We can find the x-and y-intercepts and graph the equation
x-intercept y-intercept
(y=0) (x=0)________________________________________________
5x-4(0)=-20 5(0)-4y = -20
5x =-20 -4y = -20
5x/5=-20/5 -4y/-4 = -20/ -4
x=-4 y = 5
Graph x and y on a grid and connect the points. |

**Practice:**
| Using a worksheet, students will work with a partner showing their work on individual slates with dry-erase markers |

**Accommodations:**
| Sudents functioning 4 grade levels below: will pass out color coded index cards to show partners.
students functioning 2 grade levels below: will pass out slates and dry erase markers and erasers.
On grade level students will complete worksheet by writing down solutions and turn it in. |

**Checking For Understanding:**
| Exit check |

**Closure:**
| today we learned how to graph linear equations by using x and y intercepts. |

**Evaluation:**
| 8 out 10 correct or 80% on worksheet done independently |

**Teacher Reflections:**
| How to create a more fluid lesson with students not getting distracted by the lack of structure , i.e. not using paper and pencil activity on desks. |
