Question

Help Please
What is the slope of the line that passes through the points (–1, 13) and (4, –2)?

I am dealing with analytic geometry

Answer 1

heh, if we move the points so that one of them is at the origin, we can just read the slope off of the other one

Answer 2

you really dont like the formuale do you :S lol

Answer 3

:) i dont mind it, but i tend to transpose the numbers when i try formulas

Answer 4

stack, subtract, and done is much easier for me to keep things in their correct places :)

Answer 5

i never discovered how they derived those actually o.O idk why slope is the change in y over change in x

Answer 6

by convention, we had to have some way to define it numerically

Answer 7

it could just as well be a ratio or proportion or x/y

Answer 8

i dont knoe what to do

Answer 9

*know

Answer 10

if you want a formuLA slope is \[\frac{y_2 - y_1}{x_2 - x_1}\]

Answer 11

modify your points such that one point reads 0,0 , and what you do to one you do to the other

Answer 12

thanks

Answer 13

(–1, 13) and (4, –2)
1 -13 1 -13
-----------------
0, 0 5,-15; stack y/x

Answer 14

that's a fun way to do it..

Answer 15

it keep math ALIVE! lol

Answer 16

( x1,y1) and (x2,y2)
-x1 -y1 -x1 -y1
------------------
0 , 0 x2-x1, y2-y1

y2-y1
-----
x2-x1

Answer 17

oh lol..nice one

Answer 18

cool way of looking at it
