Objective: To make line graphs to show how data change over time.

T HINK !!! What is a line graph? A graph that uses line segments to show how data change over a period of time.

Choose a proper scale and interval. Since we have a big gap in data between 0 and 44, we use a zigzag line to show the break in data.

Scale and interval Step 3 Title and labels. Graph ordered pair and connect the points.

Make a line graph for the set of data below: Distance from Lightning Distance (km) Time until thunder is Heard (sec)
