(1 point) At what points does the curve y = x - 75x - 9 have horizontal tangents? The graph has horizontal tangents at (Enter each point as an ordered pair, e.g., (2,4). If there is more than one point, enter a comma-separated list of ordered pairs. If there are no points, enter "none".) What is the smallest slope on the curve? Smallest slope is At what point on the curve does the curve have this smallest slope? Smallest slope occurs at Enter your answer as an ordered pair, e.g., (2,3). Find an equation for the line that is perpendicular to the curve's tangent at this point. Line is
