Golfers typically don't have access to the information used to calculate the Slope Rating, but understanding the formula makes the rating less confusing. Step 1. Use the Bogey Rating of the course. Ask at the golf course or contact the regional golf association that did the on-site rating.

Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b.

In this lesson, the slope of a line segment connecting two point will be measured and a general formula for finding the slope will be developed and used. The line segment shown below connects the points (1, 2) and (3, -2). As we look at this diagram from left to right, the segment slopes downward. We will define a negative number to describe the downward slope and how steeply this line ...

Answer (1 of 2): Start with the slope-intercept form, y=mx+b. We know what the slope is. Can we find what b is? We are given a point (x_1, y_1) on the line. Plug these into the equation: y_1=mx_1+b And solve for b: b = y_1-mx_1. Now put this back in the slope intercept formula where b was....m=. Where m is the slope of the line. The numerical value for slope can be expressed as a ratio or fraction. The numerator will contain the difference of y-values, and the denominator will contain the difference of x-values. The above slope formula is conceptually defined as the rise overrun.
