U: I understand that proportional relationship is when A proportional relationship is a relationship between two variables where their COP is constant, where the COP is the constant of proportionality. I also understand what the origin of a graph is; the origin is (0,0), where you start at (0,0), and then a line on the graph goes through the graph, then it means the graph is proportional.
N: I learned what ratio, reciprocal, table, proportional relationship, constant of proportionality, variable, equation, graph, axis, and ordered pairs are, and I can define each vocabulary term on this proudly without any mistakes.
I: The most interesting thing in this unit is how to use different methods to find the COP of the graph, table, or description. For example, to find the COP of the table, you use the method y over x so which means you divide y by x to find the COP of the table. Another example is how to find the cop of the graph. You look at the graph and define what the y and x are, and use the same method to find the COP.
T: The trickiest thing I found in this unit is understanding how to write a correct equation for the description, table, or graph is but overall I improved my skills and overcame this trick.
