EQ: How do you display, analyze, and interpret a line graph?

A line graph: uses a series of line segments to show changes in data. shows changes over time: – Days, years, hours, decades, etc.

Parts of a line graph Title X axis label Y axis label Interval EQ: How do you display, analyze, and interpret a line graph?

Steps to make a line graph Step 1: Step 2: Step 3: Step 4: Step 5: Draw your horizontal and vertical axis Choose and label your scale (interval) Put a single dot at each data location Connecy each dot. Label your graph.
