Convert from parametric to rectangular:  x = t - 4  and y = 2t + 1
Hint:  Solve for t and then substitute into the "y" equation.

• y = 2t - 4
• y = 2x + 9
• y = 2x + 4
• y = 2t - 3

Which set of parametric equations satisfies the given data table?

• x(t) = t³ - 1
  y(t) = 2t
• x(t) = t³ - 1
  y(t) = t + 2
• x(t) = t + 8
  y(t) = t + 2
• x(t) = t + 8
  y(t) = 2t

Eliminate the parameter:
x = 8 + 2cos(t)
y = -6 + sin(t) 

• (x + 8)²/4 + (y + 6)² = 1
• (x - 8)²/4 + (y - 6)² = 1
• (x - 8)²/4 + (y + 6)² = 1
• (x - 8)²/2 + (y + 6)² = 1
