Graphing What is a Graph? Visual representation of the relationship between two or more variables. WHAT THE ?!?! Drawing that shows how different things affect each other. Ordered Pairs (X,Y) EX: (-1,3), (2,5), (0,0)

Graphs & Tables TABLE: –Chart that shows ordered pairs. WHY Graphs? –Easy to see relationships.

Different Graphs 1.Bar Graph –C–Comparing categories 2.Pie Chart –C–Comparing parts of a whole 3.Line Graph –C–Comparing 2 things that change together –(–(most common in science!)
