1. linear graph A graph in which the data points yield a straight line.

2. line of best fit

3. A smooth line that reflects the general pattern of a graph.

4. bar graph A graph that shows a relationship between separate but related items. Bar graphs need: ◦An x-axis and a y-axis ◦A numbering pattern on the y-axis ◦Categories on the x-axis ◦Labels for both axes (metric units in parentheses) ◦A descriptive title

5. circle graph A graph that shows how parts relate to a whole. Circle graphs need: ◦A circle to represent 100% of the data ◦Wedges to represent each category ◦A key to identify each wedge ◦A descriptive title

6. line graph A graph that shows a change over time. Line graphs need: ◦An x-axis and a y-axis ◦Numbering patterns on both axes ◦Labels on both axes (with metric units in parentheses) ◦A line that represents the data ◦A descriptive title
