## MoonlitFate one year ago Consider the parametric equations below. x = 1 + 2t, y = 4 − t^2 Eliminate the parameter to find a Cartesian equation of the curve.

solve one equation for "t" , then substitute it into other equation.

$x = 1+2t \rightarrow t = \frac{x-1}{2}$ $\rightarrow y = 4 - (\frac{x-1}{2})^2$
