Eliminate the parameter. x = t2 + 1, y = t2 - 1

x - y = 2

Step-by-step explanation:

The given equations are x = t² + 1 and y = t² - 1

We have to eliminate the parameter t from these equations.

Since x = t² + 1

t² = x - 1

and y = t² + 1

t² = y - 1

Now we equate both the equations

x - 1 = y - 1

x - y = 1 + 1

x - y = 2

Therefore, answer is x - y = 2
