If three points are given then how do you prove that they are collinear?
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.
What is the slope of the line between the two points -1-4 and 3-5?
The points are (-1, -4) and (3, -5). The change in 'x' is 4. The change in 'y' is -1. The slope of the line is dy/dx = -1/4 = -0.25
What is the slope of the line through the points 70 and 91?
Assuming the two points are (7,0) and (9,1); then the slope is: slope = (1-0) / (9-7) = 1/2
What is the slope between (36) and (1-2)?
If you mean points of (3, 6) and (1, -2) then the slope is 4
What is the slope between (-1-11) and(-6-7)?
Points: (-1, -11) and (-6, -7) Slope: -4/5
