The slope is calculated as: y1-y2/x1-x2 given two sets of points

You need two coordinates, not one, to specify a point. To calculate the slope, simply calculate (difference in y-coordinates) / (difference in x-coordinates).
Using any two points, calculate the differences in the Y and the X coordinates. Then take the difference between the Y and divide it by the difference in the X. Example: Points (1,3) and (4,9) are on a line. Determine the slope of the line. X coordinates: 1 and 4. 4-1 = 3 Y coordinates: 3 and 9 9-3 = 6 Slope = Y/X = 6/3 = 2 The slope is 2
No. If you have more than two points for a linear function any two points can be used to find the slope.
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.
it is called the slope
