#### Answer

The different sets of parametric equation are: $x=t,y=2t-5\text{ and }x={{t}^{3}},y=2{{t}^{3}}-5$ (other answers are possible.)

#### Work Step by Step

Let us consider, $x=t$, then $y=2t-5$ Again, $x={{t}^{3}}$, then $y=2{{t}^{3}}-5$ Thus, $x=t,y=2t-5$ and $x=\,{{\text{t}}^{3}}$, $x={{t}^{3}},y=2{{t}^{3}}-5$ are two different sets of parametric equations.
