1. Change in y over change in x. For a linear equation, this is just m = (y2-y1)/(x2-x1) where (x1,y1), (x2,y2) are any two points on the line.
2. Evaluating the tangent of the angle relative to horizontal. For example, if a ramp has a 10 degree angle above horizontal, then the slope is tan(10).
3. For any differentiable function y in terms of x, dy/dx gives the expression for the slope of a tangent line through a point on y. If y = x3+1, then dy/dx = 3x2, and at the point (1,2), dy/dx = 3, so the slope at this point is 3. Finding the derivative of a function is very similar to finding the slope of two points on a function that are infinitely close together.

The formula for finding the slope of the line is this: m = (Y2-Y1)/(X2-X1)
1.) Triangle method 2.)Formula- Y2-Y1 -------- X2-X1 3.)two points
y = mx + b where m is the slope and b is the y-intercept.
The equation of slope intercept form is y=mx+b. This would be used in finding the slope of an object and is the most efficient way to date in doing so.
-- Measure how far the slope rises in 100-ft of horizontal distance.-- That number is the percent of slope, or the "grade".-- If you want the angle of the slope, divide the number by 100, and look upthe "arctangent" of the answer in a table or on a calculator.
