The formula for finding slope when two points are given is,

(The two points are (x1, y1) and (x2, y2).)

Slope = (y2-y1)/(x2-x1).

Using this formula, we can find the slope of the given points.

Thats a beautiful formula given by Prakash Panner. As simple as that.

For any doubts on the formulae, you can always check our formulas section.

And as PP said, mathematicians work on formulas, the soultions would also be in formulas. Not a detailed solution set to all the problems, he he

Character is who you are when no one is looking.
