M= Slope
M=(Y1-Y2)/(X1-X2)
If you have two points on a graph, say (3,7) and (2,5), then the "Y" variable would be the second number in each point and the "X" variable is the first number.
For example:
M= (7-5)/(3-2)
M=2/1
M=2, so the slope of a line between points (3,7) and (2,5) is 2.
Note you can pick either point to be point "1" or "2":
(5-7)/(2-3) = (-2)/(-1) = 2, as well.

how to find the slope of the line between the two points (-1,2) and (3, -6). can you plaese show how
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
Since the line is horizontal, the slope is zero.
what is the slope of the line containing points (5-,-2) and (-5,3)? 2
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).
