The distance between the points can be calculated by using the difference in the x coordinates, the difference in the y coordinates and Pythagoras. distance = sqrt((difference_in_x_coords)2 + difference_in_y_coords)2) So for the points (-1, 1) and (1, -1) the distance between them is: sqrt((-1 - 1)2 + (1 - -1)2) =sqrt(22 + 22) =sqrt(4 + 4) = sqrt(8) ~= 2.83
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.
because voltage is the 'electrical potential difference'. since a "difference" can only be evaluated between two points so is voltage :)
(Distance between the points)2 = (difference of the two x-values)2 + (difference of the two y-values)2
Points: (-1, 2) and (3, 3) Slope: 1/4
To find the slope we need to divide the difference in rise between these two points by the difference in run between them. The difference in rise equals: 3-2 = 1. The difference in run between these points equals: 2-4 = -2.Now we just divide 1/-2 and we get the slope of the line formed by these two points: -0.5
The distance between the points can be calculated by using the difference in the x coordinates, the difference in the y coordinates and Pythagoras. distance = sqrt((difference_in_x_coords)2 + difference_in_y_coords)2) So for the points (-1, 1) and (1, -1) the distance between them is: sqrt((-1 - 1)2 + (1 - -1)2) =sqrt(22 + 22) =sqrt(4 + 4) = sqrt(8) ~= 2.83
No. Here is an example: calculate the slope between points (1,1) and (3,2). (Delta y) / (Delta x) = (2-1) / (3-1) = 1 / 2 (Note: "Delta" means difference in some value. We are calculating the difference in coordinates between two points.) Swapping the points, you get: (Delta y) / (Delta x) = (1-2) / (1-3) = (-1)/(-2) = 1/2 As you can see, swapping the points simply changes the sign in the numerator and in the denominator. The final result is the same.

The distance between two points is Square root of [ (difference in their 'x' coordinates)2 + (difference in their 'y' coordinates)2 ]
