Graphing One Variable Lines

It’s always the easy things that we tend to mess up.  Welcome to the world of graphing one variable lines.  For many years as a math teacher I have seen students confuse these basic line equations for no other reason they could not remember the simple formulas.  So please take it from me that you can confuse these basic linear equations.  If you can remember that x= a number is a vertical line and y = a number is a horizontal line then you should be fine…I hope.  Good luck!




some key topics that involve graphing one variable lines:

* ordered pairs
* vertical line test
* slope
* slope-intercept formula
