Please just help with the bolded questions Prelab 1: Consider the following ordered pairs of numbers to show a direct relationship: X y 2 6 3 9 5 15 9 27 Make a graph of y vs. x using these ordered pairs. Mathematically determine if the relationship between x and y is direct (that is, y=Cx) or inverse (y=C/x) where C is a constant in both cases. In the process, determine the value of the constant C. Show your work. As the x-value doubles and triples, describe how the corresponding y-value changes. (e.g., the y-value doubles, triples, halves, quarters) A direct variation is one that follows a straight line through the origin. The general formula would be y = mx+b. In this experiment, we will be describing it as y = Cx (where C is a constant). Why are the two expressions the same in this case? What happened to the "b" term?
