7. GRAPH GIVEN THE GRAPH SLOPE Determine the SLOPE of a LINE

8. GRAPH GIVEN THE GRAPH

12. TABLE GIVEN A TABLE SLOPE Interpret the SLOPE of a LINE

13. GIVEN A TABLE Interpret the SLOPE of a Line: Step 1: Focus on only 2 sets of input/output data in the table Step 2: Label y 2, y 1, x 2, x 1 Step 3: Write Slope Formula Step 4: Plug coordinates into the Slope Formula Be sure to place numbers in the correct spots Step 5: Simplify to solve for m

14. SLOPE TABLE What do you notice about finding the SLOPE when using a TABLE versus another method we have covered? TABLE SLOPE FORMULA TABLE follows the same procedures as when we use the SLOPE FORMULA & 2 POINTS. SLOPE FORMULA TABLE 2 specific points listed to calculate (Basic Skill Drill) Several points organized to choose from (Real Life Application)
