$x = t + 1$ , $y = \sqrt{t}$

Step 1

Set up the parametric equation for $x (t)$ to solve the equation for $t$ .

$x = t + 1$

Step 2

Rewrite the equation as $t + 1 = x$ .

$t + 1 = x$

Step 3

Subtract $1$ from both sides of the equation.

$t = x - 1$

Step 4

Replace $t$ in the equation for $y$ to get the equation in terms of $x$ .

$y = \sqrt{x - 1}$

Step 5

Remove parentheses.

$y = \sqrt{x - 1}$
