Q. Evaluate the expression for b=−1b = -1.\newlineWrite your answer in simplest form.\newlineb−3b−8=\frac{b - 3}{b - 8} = ____
  1. Identify Expression: Identify the expression after substituting b=−1b = -1\newlineSubstitute −1-1 for bb in b−3b−8\frac{b - 3}{b - 8}.\newline(−1)−3(−1)−8\frac{(-1) - 3}{(-1) - 8}
  2. Substitute and Simplify: Evaluate (−1)−3(-1) - 3(−1)−3=−4(-1) - 3 = -4Numerator: −4-4
  3. Evaluate Numerator: Evaluate −1−8-1 - 8−1−8=−9-1 - 8 = -9Denominator: −9-9
  4. Evaluate Denominator: −4−9-\frac{4}{-9}\newlineRewrite the fraction in simplest form.\newlineSince −4-4 and −9-9 have no common factors other than 11, the fraction is already in its simplest form.\newline=49= \frac{4}{9}
