Question

Roberta uses 5 beads for every 3 inches of string while making necklaces which graph best represents the ratio of necklace string to beads used

Answer 1

5 beads are used for every 3 inches, that makes 5/3 beads per inch.

Thus that can be modeled by the graph y=x*5/3 where x is the number of inches and y is the number of beads.
