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.
