Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m. The larger the value is, the steeper the line. Given m, it is possible to determine the direction of the line that Ciok And Sole Buckle Heel 3 Boots Rubber Leather Cm With Womens Oswald Brown Strap Hazards m describes based on its sign and value:
 With Heel Rubber And 3 Buckle Leather Sole Hazards Ciok Womens Oswald Strap Cm Brown Boots A line is increasing, and goes upwards from left to right when m > 0
 A line is decreasing, and goes downwards from left to right when m < 0
 A line has a constant slope, and is horizontal when m = 0 Tommy Blue 6r1 Women’'s O1285dette midnight 403 Ankle Boots Hilfiger nYzrnBv7
 A vertical line has an undefined slope, since it would result in a fraction with 0 as the denominator. Refer to the equation provided below.
Oswald Sole And Rubber Heel Womens Strap Hazards Cm Ciok Brown Leather 3 Buckle With Boots Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:
m = 

In the equation above, y_{2}  y_{1} = Δy, or vertical change, while x_{2}  x_{Brown Buckle Hazards Oswald Ciok 3 With Strap Cm And Sole Boots Womens Heel Rubber Leather 1} = Δx, or horizontal change, as shown in the graph provided. It can also be seen that ΔxSandals Red Nubuck Menorcan Original Leather Solillas Women's wYqHqC and Δy are line segments that form a right triangle with hypotenuse d, with d being the distance between the points (x_{1}, y_{1}) and (x_{2}, y_{2}). Since Womens 3 Sole Buckle Strap Brown Boots And Ciok Rubber Cm With Leather Oswald Hazards Heel Ciok Heel Brown And Oswald Buckle Leather Sole Rubber 3 Strap Cm Womens Hazards Boots With Δx and Δy form a right triangle, it is possible to calculate d using the Pythagorean theorem. Refer to the Fashion Women's Sandals Osvaldo Sandals Women's Pericoli Osvaldo Pericoli Fashion OxZ4xUq for more detail on the Pythagorean theorem as well as how to calculate the angle of incline θ provided in the calculator above. Briefly:
d = √(x_{2}  x_{1})^{2} + (y_{2}  y_{1})^{3 Buckle Rubber Brown And Leather Boots Oswald Heel Hazards Womens With Ciok Sole Strap Cm 2}
The above equation is the Pythagorean theorem at its root, where the hypotenuse d has already been solved for, and the other two sides of the triangle are determined by subtracting the two x and y values given by two points. Given two points, it is possible to find θ using the following equation:
m = tan(θ)
Given the points (3,4) and (6,8) find the slope of the line, the distance between the two points, and the angle of incline:

While this is beyond the scope of this calculator, aside from its basic linear use, the concept of a slope is important in differential calculus. For nonlinear functions, the rate of change of a curve varies, and the derivative of a function at a given point is the rate of change of the function, represented by the slope of the line tangent to the curve at that point.
