Answer: y = x - 5

Explanation:

"Eliminate the parameter" means we want to eliminate the extra variable and rewrite it ias one equation that only contains x, y, and possibly a constant.

The extra variable in the equations is "t". Manipulate one of the equations to solve for t². Then substitute t² = _____ it into the other equation.

x = t² + 3 → x - 3 = t²

y = t² - 2

y = (x - 3) - 2

y = x - 5
