Graphing A graph is a visual display of information Graphs are used to interpret data and information quickly A student noticed that his shower is covered in a strange cloudy slime. His friend tells him that coconut juice will get rid of the strange slime. The student decided to test this out and sprayed half the shower with the coconut juice and the other half with water. After 3 days of cleaning the side of the shower sprayed with coconut juice had no residue of the cloudy slime.
