This week in math 10 we started a review of linear relations. 1 thing that I learned was that there are 2 types of variables discrete and continuous. The difference between these is that discrete is a line of dots that are not connected and are counting variables an example is people. continuous is a variable being measured such as weight, volume and mass. examples of these different types of variables are. the first graph is an example of a decrete and the second is  an example of continuous
