Write Parametric equations of -3x+1/2y=2
- Pre-Calculus - Reiny, Friday, February 28, 2014 at 9:19pm
we know x =rcosŲ and y = rsinŲ
-3rcosŲ + (1/2)rsinŲ = 2
-6rcosŲ + rsinŲ = 2
r(sinŲ - 6cosŲ) = 2
r = 2/(sinŲ - 6cosŲ)

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
