In 2011, a collector of sports memorabilia purchased specific baseball cards as an investment. Let y represent each card’s resale value (in dollars) and x represent the number of years since purchase. Each of the cards’ resale values after 0, 1, 2, 3, and 4 years could be modeled by linear functions as follows:


Card A: y=3−0.8x ,Card B: y=7+2.7x ,Card C: y=15+0.9x ,Card D: y=14−3.1x ,Card E: y=5+0.25x


Select ALL cards that are decreasing in value.


Question 3 options:
