A projectile is shot at a hill, the base of which is 290 m away. The projectile is shot at 60° above the horizontal with an initial speed of 78 m/s. The hill can be approximated by a plane sloped at 21° to the horizontal. Relative to the coordinate system shown in the following figure, the equation of this straight line is
