(Sci Mat) Linear Graphing Analysis

Linear graphs are :

• straight lines
• circles
• curves
• none of the above

The purpose of graphs, charts and tables is to

• help scientists visualize results from an experiment.
• make the experiment look nice.
• practice what I learned in Math class.
• Practice my drawing skills.

Which statement matches the graph?

• Taylor can write 6 words per minute
• Taylor can write 25 words per minute
• Taylor can write 50 words per minute
• Taylor can write 150 words per minute
