A remote control car starts at the point (3,0) and moves northeast along the line y = 3x-9. At the point (6,9), it makes a 90° turn and starts to move southeast.


9. Find the equation of the line the car is moving along after the 90° turn.
a. y = 1/3x -9
b. y = -1/3x -9
c. y = -3x -11
d. y = -1/3x + 11

10. What are the coordinates of the car when it hits the line y = 0?
a. (0, 11)
b. (33, 0)
c. (3, 0)
d. (34, 0)
