3. Find the slope of the line through the points: (-2,3) and (4,8)

4. Find the slope of the line through the points: (7,-6) and (-5,2)

5. Find the slope of the line through the points: (1,2) and (5,2)

6. Find the slope of the line through the points: (2,1) and (2,5)

7. Find the slope of each line: slope of line A _____ slope of line B _____ slope of line C _____ slope of line D _____ A CD B

8. Midpoint The midpoint can be found on a number line and on a coordinate plane. The formulas for both are: M (on a # line) = M(on a coordinate plane)=

9. Find the midpoint of ( -2, -1 ) and ( 4, 2 ). M=M=
