Q. Line bb has a slope of 49\frac{4}{9}. Line cc has a slope of 94\frac{9}{4}. Are line bb and line cc parallel or perpendicular?\newlineChoices:\newline(A) parallel\newline(B) perpendicular\newline(C) neither
  1. Calculate slopes: Line bb slope: 49\frac{4}{9}. Line cc slope: 94\frac{9}{4}. Are these the same or opposite reciprocals?
  2. Compare reciprocals: Reciprocal of 49\frac{4}{9} is 94\frac{9}{4}. Since line cc's slope is 94\frac{9}{4}, they are opposite reciprocals.
  3. Determine perpendicularity: Opposite reciprocals mean the lines are perpendicular.
