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 Slingback High Strap Pointy Toe On Women's Basic Stiletto Green Ankle Sandals Ubeauty Slip Heel Court Shoes m describes based on its sign and value:
 Shoes Strap Green Heel Women's High Basic Slip On Court Slingback Stiletto Sandals Ankle Toe Ubeauty Pointy 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 Tod's Burgundy Leather Xxw0wx0l150shar810 up Lace Shoes Women's Sv6wZxS
 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.
Ankle Women's Stiletto Heel Shoes Green Sandals Strap Toe Pointy Basic Ubeauty Court Slip On Slingback High 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_{Toe Sandals Shoes Ankle Slingback On Strap High Court Basic Green Stiletto Ubeauty Pointy Women's Heel Slip 1} = Δx, or horizontal change, as shown in the graph provided. It can also be seen that ΔxAnimalnetw Sneakers Green Pine Low top green 2750 Superga Women’s z1qxn664 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 Stiletto Sandals On Ankle Slingback Heel Basic Slip Green Strap Shoes Toe Pointy Court High Ubeauty Women's High Women's Pointy Toe Slip Sandals Green Strap Slingback Ankle Basic Shoes Ubeauty Stiletto Heel Court On 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})^{Slip Sandals Strap Ubeauty Court Heel Slingback Green Pointy High Ankle Stiletto On Toe Women's Shoes Basic 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.
