TRANSCRIPT

  • Lesson 4.3 Graphing Horizontal & Vertical LinesMr. Beltz &Mr. Sparks

  • HorizontalThink Horizonleft & right.

  • VerticalThink of Mr. Beltzs Vertical Jump in basketball. (Up & Down)

  • Linear equations ReviewAll linear equations can be written in the form: Ax + By = C

  • Horizontal LinesAx + By = C

    When A = 0The equation reduces to By = C

    This results in a HORIZONTAL LINE(Example 1)

  • Vertical LinesAx + By = C

    When B = 0The equation reduces to Ax = C

    This results in a VERTICAL LINE(Example 2)

  • SummaryIf y = b Horizontal LineIf x = a Vertical Line

  • Writing an Equation of a line.The graph is a vertical line. The x-coordinate is always -2.

    The equation of the line is x= -2

    (Example 3a)

  • Write an Equation of a line.The graph is a horizontal line. The y-coordinate is always 4.

    The equation of the line is y=4.

    (Example 3b)

  • PracticeComplete #1-8 on pages 216-217.
