How much slope and how long of a run? For short distance, up to 12 feet, and 12 inches of drop, you cut a 2x12 at the right slope and use them for the floor joist. For longer runs or greater slope, Use 2x6 level and use 2x4 legs under them.
The slope of a horizontal line is zero. It has a slope, but slope = 0 and this makes it different from a vertical line which has a slope that is undefined because you cannot divide 0 over 0 which is how much a vertical line rises and runs.Ways to find slope:(y2-y1)/(x2-x1 )orrise/run
The slope is the magnitude of the line upwards or downwards, commonly referred to as "rise over run". The rise is how much the graph goes up in a certain distance, and the run is how much the graph goes over horizontally that same distance. To find the slope in that situation, you have to divide the rise by the run.
This is known as the slope. It is how you go up divided by how much you go in the horizontal direction. The letter m is often used for slope.
Any line, except a vertical line has a well defined slope. It cannot be undefined. In much the same way as you cannot be undefined!
