Today PJ and talked about variables. We discussed how the word variable has the root word vary which means to change. In Algebra, we frequently use ‘x’ as a variable and it can represent all kinds of numbers: positive, negative, zero, fractions, etc. Today we discussed how we can have problems with two variables, where one outcome is dependent on the other. For example, money earned (in dollars) depends on the amount of time (in hours) one has worked. We identified the dependent variable as Dollars and the independent variable as hours. We moved into our Savvas online account and pulled more situations where PJ had to identify the dependent and independent variables. He did an excellent job with this lesson.
