Slope

• The steepness of a line.
• Found by doing

4
Finding Slope from Tables

• The values in the table, when graphed form a
  line.
• Graph the values on a coordinate plane.
• Draw a line.
• Find the slope of the line.

5
Finding Slope from Tables

• Notice the change in the y values compared to
  the change in x values.
• What is the slope?
