### Example Question #19 : Parametric Form

Convert the following parametric function into rectangular coordinates:

**Possible Answers:**

**Correct answer:**

To eliminate the parameter, we can solve for t in terms of y easiest:

Next, substitute all of the t's in the equation for x with what we defined above:

To finish, subtract 3, multiply by 4 and take the square root of both sides. We need plus or minus because both positive and negative squared give a positive result.
