Any line that contains the graph of a collection of equivalent ratios goes through the point (0, 0); however, the point (0, 0) is not a member of the collection.
What to look forUnit rates are suggested in some of the questions as good strategies for solving problems. Students should remember that adding two columns in a ratio table produces another ratio equivalent to those added.
Mark and Steve bike at the same rate. If it takes Steve
hour to bike 6 miles, how long will it take Mark to bike 8 miles?
