Question

Whats the formula for doing slope with only this. (5,0) and (6,8)?

Answer 1

\[ m = \frac {y_2 - y_1} {x_2 - x_1} \]
The above is the slope through the line passing through two points (x₁,y₁) and (x₂,y₂).

Answer 2

okay... thnk you.. :)\

Answer 3

yep; subtract the points and stack y over x

x , y
( 5 , 0 )
-( 6 , 8 )
---------
-1, -8; slope = y/x = -8/-1 = 8

Answer 4

why are yoiu saying all this stuff is negative?

Answer 5

it doesnt matter how you subtract the points; in the end it all comes out to a slope of 8 for example:

( 6 , 8 )
-( 5 , 0 )
---------
1 , 8 ; slope = y/x = 8/1 = 8

Answer 6

what about this .... (4,-3) and (6,-4)

Answer 7

what do you get when you subtract one point from the other?

Answer 8

i am stuck on -4--3

Answer 9

(4 , 3)
-(6 , -4)
---------
-2 , 7 right?

4-6 = -2; 3--4 = 7

Answer 10

but its -4 and -3

Answer 11

your right, I missed the - :)

Answer 12

-4 - (-3) = -4 + 3 = -1

Answer 13

(4 , -3)
-(6 , -4)
---------
-2 , 1 then :)

Answer 14

(6 , -4)
-(4 , -3)
---------
2 , -1 is just as good

Answer 15

ok

Answer 16

i like to stack the points becasue I tend to switch out the x and y values if I do it the other way

Answer 17

okay i am in an advanced math class and i just get stuck on some

Answer 18

remember; when ever you get the same sign twice, its a +

4--3 means 4+3

5++2 mean 5+2

whevenever you get opposite signs together, you go negative

6-+2 means 6-2

3+-5 mean 3-5
