Create two parametric equations where x is a function of t and y is a function of t.

1. First plot t versus x, then plot x versus y. What kind of regression should you use for each one based on your graphs?

2. Use your calculator to create a formula for the model you have chosen. Enter the ordered pairs into lists and have the calculator create the line of best fit for your model. For example, if your path appears to be exponential, you will have a model of the form y = ab^x using the ExpReg feature on the calculator.

3. Write your final equations:

 • x(t) =
