This question is not clearly stated. Many shapes have lines that decrease and/or increase just the same. A line that decreases reveals a decreasing function; a line that increases reveals an increasing function.

I just want to add that whenever they ask you to solve for a letter, any letter, it means to isolate the letter just like Ms. Sue easily did. Do you see that l has been isolated on the left side of the equation? This is very important to keep in mind in any math course. Also, ...

Algebra
For question one use: P( A or B) = P(A) + P(B) - P(A and B) The rule for OR takes into account those values that may get counted more than once when the probability is determined. Let P = probability Let A = biographies Let B = reference book Can you finish?
