You just have to substitute values of slope and vertical distance in formula and get value of horizontal distance. Similarly, any one of them can be found if other two are given. For instance, if you have a slope given in Percentage as 10 % and a vertical distance of 50 feet, then equation will look like:
The horizontal line is known as X-axis and the vertical line is known as Y-axis. The coordinate point (x, y) on the Cartesian plane says that the horizontal distance of the point from the origin is x, and the vertical distance is y. If the sign of x is positive the point is on the right of the origin, else it is on the left.
