4. Using Slope Intercept Form to Graph Day 2

6. 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.

7. 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.

8. Practice
Graph.
y = 2x + 1
x = 6
y = 5

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