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