9.5 parameters

The main problem here is that I literally have no clue how to structure the equation to get the right answer. Even the first problem in the book (find explicit relationship by removing parameter: x = t +1, y = t - 1, 0<=t <=2. this ends up as y = x - 2, 1<= x <= 3) completely dumbfounds me. The example given in the book uses simply says, We use this theorem and then this is the answer there are no steps for me to follow, and I have no clue how to find the relationship.

I understand what the parameter is roughly. I need to find the relationship between the two problems, then simplify it, turning the two equations into one. However, what I do not understand is what way (if there is one) to set up the two problems to become one. How does x = t +1 and y = t -1 become y = x - 2 ?
@& Solve one equation for t and substitute the result into the second equation.
x = t + 1 so t = x - 1.
Thus y = t - 1 becomes y = (x - 1) - 1 = x - 2.
Once you see this I don't think you'll have a lot of trouble.
Note that there are also a lot of worked examples in the q_a_. *@
