Graphing Lines Using y = mx + b Slope Intercept

The most common way students learn to graph lines is using y=mx + b or the slope intercept method.  This is a great method because it’s straight forward and easy.  However a linear equation must be in y=mx + b form to use the slope intercept method of graphing.  Let’s look at a quick example. […]

Basic Number Operations

Listen I would not like math if we did not do anything with numbers. Well fortunately we do things with numbers like add, subtract, multiply and divide. These “things” we do with numbers are called “operations”.  Now basic operators like addition and subtraction are not the only operators in math- actually there are many, many […]

Variables

  One of the first things you learn in algebra is the concept of variables.  As you may already know a variable is simply a letter or symbol that holds the value of a number. Algebra is really like basic arithmetic but instead of adding, subtracting multiplying and dividing regular numbers we perform these same […]
