Which set of equations could be parametric equations?y= x and y= 3xy= x + 1 and y= 3x2x= t and y=3tx= 3y and y= x+1

The set of equations x = t and y = 3t could be parametric equations ⇒ 3rd answerStep-by-step explanation:Lets explain the meaning of parametric equationsA parametric equation is where the x and y coordinates are both written in terms of another letterExamples:x = 2t and y = 2 - t²x = 0.5 Ф and y = 2Ф, where Ф is measured from the positive x-axisLet us find the set of the parametric equations from the answerFist answer:∵ y = x and y = 3x∴ It is a set of linear equations Second answer:∵ y = x + 1 and y = 3x²∴ It is a set of linear and quadratic equationsThird answer:∵ x = t and y = 3t∵ x and y are represented in terms of t∴ It is a set of parametric equationsFourth answer:∵ x = 3y and y = x + 1∴ It is a set of linear equations The set of equations x = t and y = 3t could be parametric equationslearn more:You can learn more about the parametric equations in brainly.com/question/1600331#LearnwithBrainly
