Providing an example of at least five ordered pairs that do not model a function with the domain
between 0 and 20 and the range between -10 and 10 isnt that complicated really. Examples of
ordered pairs that dont model a function could be, (5,8) (2,6) (3,

The easiest way to predict if two lines on a graph will be perpendicular or not, is to examine the
graph and determine if the lines run into each other. Sometimes you will have to solve equations
and then graph the lines before being able to tell if they

On a graph you have an x-axis and y-axis. X-axis is a vertical line and y-axis is horizontal line.
When graphing a variable such as x=4 you must follow the x-axis, which on a graph would be a
vertical line. Thats probably the easiest way to explain why x=

How do you know when an equation has an infinite number of solutions?
You can always tell when an equation has an infinite number of solutions by two ways. One both
sides of the equations is exactly the same, such as 23x=23x. Whatever you substitute a val

I have been out of school for more than 22 years so this should be interesting after the long time
off and never having to do algebra since but the expression contains the variable, numbers,
constants, and operational signs but no equal sign were an equat

Week 4 Concept Check
Post your 50- word response to the following: Explain in your own words why the line x=4 is a vertical
line.
The line x =4 is a vertical line because they y value is not specified by the equation. Y can vary to any
value, while still
