If you're given two points....here's an easy way [ no "formulas" involved ]
Example ......find the slope of a line containing the points (3, 5) ( 6 , 20)
1st ... subtract the y coordinates in any order.....I'll do (20 - 5) = 15
2nd ....subtract the x coordinates in the SAME order (6 - 3) = 3
Put the first thing OVER the second
15 / 3 = 5 and that's the slope !!!!
Pretty easy, huh???
