Write Parametric equations of -3x+1/2y=2

  1. Reiny

    we know x =rcosØ and y = rsinØ

    -3rcosØ + (1/2)rsinØ = 2
    -6rcosØ + rsinØ = 2
    r(sinØ - 6cosØ) = 2
    r = 2/(sinØ - 6cosØ)

    looks good:

  2. Steve

    Reiny gave you good polar coordinates, but if all you want is parametric equations, try

    x = t/3
    y = 1 + t/2


    x = -(2+t)/3
    y = -2t
