If you mean: (2, 5) and (8, 3) then it works out as -1/3
The slope of a line that passes through two points is (difference in y) / (difference in x).
Points: (-1, -3) and (-9, 7) Slope: -5/4
Points: (3, 15) and (5, 9) Slope: -3
The slope is -2/3.
Points: (-12, -17) and (21, 5) Slope: 2/3
The slope of a line that passes through two points is (difference in y) / (difference in x).
Where are the points!
The slope is zero.
Points: (2, 1) and (5, 3) Slope: 2/3
The slope is 2.
The slope is 1/2.
Points: (0, 5) and (10, -15) Slope: -2
Points: (-2, 4) and (-6, 12) Slope: -2
Points: (-1, -3) and (-9, 7) Slope: -5/4
Points: (3, 15) and (5, 9) Slope: -3
Points: (3,-1) and (-2, -5) Slope: 4/5
Points: (-3, 4) and (7, -6) Slope: -1
