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)
