# Converting Rectangular and Parametric Equations

Not what you're looking for?

Eliminate the parameter. Find a rectangular equation for the plane curve defined by the parametric equations.

x = 3t, y = t + 7

y = 3x + 7

y = x/3 + 7

y = x/3 - 7

y = 3x - 7

Find a set of parametric equations for the rectangular equation:

y = 2x - 2

x = t/2; y = t - 1

y = 2t; 2x = t + 2

y = 2t2 - 2

x = t; y = 2t - 2

We have x = 3t, y = t + 7

Multiply the second equation by 3 on both sides, we get

3y=3t+21

As we ...
