If you mean points of (3, 6) and (1, -2) then the slope is 4
Points: (-1, -11) and (-6, -7) Slope: -4/5
0). Considering any TWO points, you can calculate the slope of the line between them like this: Slope = (difference between the y-values of the two points) divided by (difference between the x-values of the two points). Use this technique to examine your THREE points, like this: 1). Calculate the slope of the line between Point-2 and Point-1. 2). Calculate the slope of the line between Point-3 and Point-1. 3). If the two slopes are equal, then the three points all lie on the same line.
Points: (-1, -1) and (0, 0) Slope: 1
Points: )1, 1) and (3, 3) Slope: 1
-1
Points: (-1, 2) and (4, 3) Slope: 1/5
If you mean points of (3, 6) and (1, -2) then the slope is 4
To find the slope between two points: slope = change_in_y/change_in_x Thus for the points (4, 5) and (6, 8), the slope between them is given by: slope = (8-5)/(6-4) = 3/2 = 1½ = 1.5
Points: (3, -4) and (-2, 1) Slope: -1 or -x
Points: (-1, -11) and (-6, -7) Slope: -4/5
0). Considering any TWO points, you can calculate the slope of the line between them like this: Slope = (difference between the y-values of the two points) divided by (difference between the x-values of the two points). Use this technique to examine your THREE points, like this: 1). Calculate the slope of the line between Point-2 and Point-1. 2). Calculate the slope of the line between Point-3 and Point-1. 3). If the two slopes are equal, then the three points all lie on the same line.
If you mean points of (6, 6) and (2, 2) then the slope works out as 1
Points: (-1, -1) and (0, 0) Slope: 1
Points: (-3, -1) and (3, -2) Slope: -1/6
Points: )1, 1) and (3, 3) Slope: 1
If you mean points of (-2, 3) and (-7, -2) then the slope works out as 1
