Question

P= (2,3) q= (9,7) find slope and reduce

Answer 1

The slope of the line containing the points (2,3) and (9,7) is 4/7. 

Slope Formula:    y₂ - y₁         7 - 3           4
                           ------------- = ----------- = -------
                              x₂ - x₁          9 - 2           7

4/7 can't be reduced any further, so that's your final answer.
