If you define the rise and run in terms of the coordinates of two points on the line whose slope you are trying to find, then you should see that the two are exactly the same.
If you are in the mathematics field then you might be using it everyday; otherwise... not so much

1. Determine the height difference (a) between the start and end of the slope by subtracting the starting height from the final height (if it is a downhill slope the difference will be a negative number) 2. Determine the horizontal distance (b) between the starting point and the final point. If you only know the actual linear distance (c) along the slope, you can figure the horizontal distance using the Pythagorean Theorem: a2+b2=c2. For example, if the linear distance (c) along the slope from start to finish is 1000 feet, and the height difference (a) is 75 feet, then using the theorem you would have 752+b2=10002or 5625+b2=1000000. Your horizontal distance (b) would therefore be b2=994375 or b=997.2 feet 3. Divide the height difference (a) by the horizontal distance (b) and multiply by 100. This gives you the grade of the slope in percent. In the example it would be 75 ÷ 997.2 × 100 = 7.5% grade
The formula for simple (ordinary) interest on a bank deposit is Deposit Amount x Rate x Time (# of days) on Deposit.
2 + 4 + 6 + 8 + 10 = 30 In general, the sum of the first n even numbers is n(n+1). Replacing n with 5 we have 5x6 which equals 30 as we found by direct calcuation. The formula is nice when you have many numbers. For example, finding the sum of the first 100 positive even numbers would be a PAIN! But using the formula is it simply 100x101.
You can make a formula of finding the slope of an area buy first finding the equation of the line using: y - y1 = m ( x - x1 ).
you do y2-y1 over x2-x1
formula
A horizontal line has a slope of 0. If you're using the slope formula, then when the numerator is equal to 0 then the slope is 0.
using a protractor
Points: )1, 1) and (3, 3) Slope: 1
For a horizontal line, the slope is zero. Using the formula y=mx+b, where m is the slope.
Using limits and the basic gradient formula: rise/run.
yes we can calculate it by using trigonometric equation (by finding tan θ).
no
The formula for finding the midpoint of a line segment using midpoint notation is: M ((x1 x2) / 2, (y1 y2) / 2)
