The formula for slope is change in y change in x. Notice how the first skateboarder is going down a steeper ramp. Multiply this number by 100 and you have the percentage slope.
A Slope Rating is the USGA mark that indicates the measurement of the relative playing difficulty of a course for players who are not scratch golfers compared to scratch golfers.
To help imagine that you are a skateboarder about to go down a ramp. The slope will be the same for a straight line no matter which two points you pick as you know. A Slope Rating is the USGA mark that indicates the measurement of the relative playing difficulty of a course for players who are not scratch golfers compared to scratch golfers. Where m is the slope and th th is the angle made by the line with the positive x-axis.
