Question

Eliminate the parameter. x = t2 + 3, y = t2 - 2

Answer 1

Answer: y = x - 5

Step-by-step 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
