Q:

What is the formula for the gradient of a straight line?

A:

The gradient of a line (m) is calculated by finding the quotient of vertical displacement (y2 minus y1) over horizontal displacement (x2 minus x1). This means that the slope is equal to the vertical change divided by the horizontal change.

Slope is a measurement of the rate of incline or decline of a line or surface. A 10 percent slope corresponds to an incline of 10 vertical units for every 100 horizontal units traveled, while a negative 10 percent slope corresponds to a decline of 10 vertical units for every 100 horizontal units. In physics, an increase in slope equates to a decrease in the supporting force of an object, meaning gravity performs more work on it.

To convert kN/m2 to kg/m2, multiply by approximately 102 seconds squared per meter, which is 1000/9.8 seconds squared per meter. The conversion of units of force, such as kilonewtons, to units of mass, such as kilograms, assumes that the mass is subject to an acceleration, most often the acceleration of gravity, which is typically around 9.8 meters per second near the earth's surface. However, the precise figure can vary slightly with location.

A millimeter (mm) is the smallest. In order from smallest to largest they rank millimeter, centimeter (cm), decimeter (dm), and meter (m). These are all common units of length in the metric system.

To calculate the gradient of a line, divide the change in height between the beginning and end of the line by the change in its horizontal distance. Arguably the easiest way to do this is to plot the line on a pair of axes. For example, if a line started at (0,0) and ended at (4,4), its change in height would equal 4, and the change in horizontal distance would also equal 4. Divide 4 by 4 to get 1; therefore, the gradient of the line would equal 1.
