The coordinates of a car at time t are given by x = 8 - t and y = 2t - 16. As t increases, which direction and path is the car traveling?

• from left to right along the path y = 2x - 16.
• from left to right along the path y = 2x.
• from right to left along the path y = -2x.
• from left to right along the path y = -2x.

Given the Rectangular Coordinate
(-7√2, 7√2), write the point as a polar coordinate for 0≤θ≤2π

• (14, π/4) , (-14, π/4)
• (14, 7π/4) , (14, π/4)
• (14, 5π/4) ,
  (-14, 3π/4)
• (-14, 7π/4),
  (14, 3π/4)
