Graphing Horizontal and Graphing Horizontal & Vertical Lines Section 4.3 Graphing Horizontal and Vertical Lines Goal: Graph horizontal and vertical lines.
Vertical Lines: Written in the form of x = h. Horizontal Lines: Written in the form of y = k. (constant function) y = 2 x 0x + y = 2 y 0 0(0) + y = 2 2 (0, 2) 1 0(1) + y = 2 2 (1, 2) 5 0(5) + y = 2 2 (5, 2) –3 0(–3) + y = 2 2 (–3, 2) (0, 2) (5, 2) (–3, 2) (1, 2)
x = 6 x x = 6 y 6 x = 6 0 (6, 0) 6 x = 6 1 (6, 1) 6 x = 6 5 (6, 5) 6 x = 6 -3 (6, –3) (6, 5) (6, 1) (6, 0) (6, –3)
Horizontal Vertical y = 2 y = –5 y = 8 x = 6 x = –4 x = . 5
