If you mean: (y2-y1)/(x2-x1) and (y1-y2)/(x1-x2) then either works out the same.
you do y2-y1 over x2-x1
To find the slope of a line passing through a given pair of points is found by using the point slope formula. Y(2)-Y(1) over x(2) -x(1).
When you graph a line using only the slope and a point, you start by graphing the point.
The slope intercept form is found by using this formula: y=mx+b. so the coefficient of x is the slope or 'm'. You can find the slope using this formula: y2-y1/x2-x1 wherein the first y is the y value of your coordinate (x,y) and the y2 is the second y value of the coordinate (x,y) The same applies to the x values. The first x value is the first part of your ordered pair ((x),y)..the x part. The second x value is the other 'part' of the ordered pair given to you...or ((x),y). If you're only given one x,y value, then you will need another formula y-y1=m(x-x1) and to find the slope. You only need fill in one of the values, the x1 and y1 values with your given point. You will almost always be given a slope and a point, or a graph which you can figure out the slope for, or two points.
(2,4) (1, -3) First, find the slope, which is change in y over change in x. from -3 to 4 is 7 from 1 to 2 is 1 The slope is 7. Using the point slope formula you can find it in slope-intercept form. point-slope is y-y1=m(x-x1) *Number 1's are subscripts and m=slope* [You use a point for y1 and x1] y- (-3) = 7 (x-1) y+3 = 7x - 7 y= 7x -10
formula
A horizontal line has a slope of 0. If you're using the slope formula, then when the numerator is equal to 0 then the slope is 0.
Points: )1, 1) and (3, 3) Slope: 1
For a horizontal line, the slope is zero. Using the formula y=mx+b, where m is the slope.
You can make a formula of finding the slope of an area buy first finding the equation of the line using: y - y1 = m ( x - x1 ).
Using limits and the basic gradient formula: rise/run.

3 is the slope. The formula is "y = mx + b," and since 3 is in the "m" spot, 3 is our slope. You can also find the slope using two given points and figuring out the difference.
If you define the rise and run in terms of the coordinates of two points on the line whose slope you are trying to find, then you should see that the two are exactly the same.
you do y2-y1 over x2-x1
A protractor.
The slope of the line passing through the points (-4, -6) and (-3, -1) can be calculated using the formula: slope = (change in y)/(change in x). Substituting the given coordinates, we find that the slope is 5/1, or simply 5.
