Slope from Tables

Ms. May

​NC.8.F.4

​EQ: How can slope be determined from a graph, table or ordered pairs?

​To find Slope from Tables

​Remember: Slope is a RATIO between the difference in Y-values, divided by the difference in X-values. This same process can be applied to tables.

​Steps

1. ​Find Difference in Y values

2. ​Find difference in X values

3. ​Divide the difference in Y-values by difference in X-values

4. ​Reduce the fraction if possible.
