Using Slope Intercept Form to Graph Day 2

Special Graphs Graph y = 4 Notice there is only a y in this equation. There is no x. To graph you go to the 4 on the y axis (because y = 4) and draw a horizontal line.

Special Graphs Graph x = 3 Notice there is only a x in this equation. There is no y. To graph you go to the 3 on the x axis (because x = 3) and draw a vertical line.

Practice Graph. y = 2x + 1 x = 6 y = 5 black blue red

Closure When graphing special graphs how do you know when to draw a horizontal line? A vertical line?
