M= y1-y2/x1-x2
(ps... y=mx+b is the formula for finding the y-intercept)

the formula for a line is y=mx+b
y is the point that the line passes through on the y or vertical plane.
x is the point it crosses through on the x or horizontal plane
b is the y intercept of the line. The place the line crosses the y axis when x = 0
m is the slope. The gradient of the line that show rise over run, or the change in y divided by the change in x. Show by: (y2 - y1)/(x2 - x1)

Slope = (y2-y1)/(x2-x1), meaning if you have 2 points to form a line..you can devide the difference of y and x between two points. It is the tangent of the line formed by that two points.

Rise over run.
That's what slope is. To figure the slope of a line it's y=mx+b

if you have a function y the slope is the first derivative at the point
ex y=x^2 at point x=1
the derivative dy/dx = 2x^2 at point 1 dy/dx= 2

slope is m
m= change in y 0ver the change in x
m=y-y1/x-x1

slope:
y = mx + b
y2 - y1 divided by x2 - x1

(x1, y1)
(x2, y2)
y2-y1
--------
x2-x1
