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 **m** describes based on its sign and value:

- 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
- 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.

### Slope Calculator Solutions

Input two points using numbers, fractions, mixed numbers or decimals. The slope calculator shows the work and gives these slope solutions:

- Slope m with two points
- Graph of the line for y = mx + b
- Point Slope Form y – y
_{1}= m(x – x_{1}) - Slope Intercept Form y = mx + b
- Standard Form Ax + By = C
- y-intercept, when x = 0
- x-intercept, when y = 0
