The formula for slope by two points is: (y2-y1)/(x2-x1).
More simply put, rise over run: The increase or decrease in height divided by the distance moved to the right.
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
Where are the points!
The slope of a line that passes through two points is (difference in y) / (difference in x).
We know that its slope is negative, but without an equation or some points the line passes through we can't determine the actual value of the slope.
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
