Question

find the slope of line containing pairs of points (-6,-10) (-12,-11)

Answer 1

(y2-y1)/(x2-x1)

Answer 2

the slope of the line containing points(x1,y1)and(x2,y2) is
m=(y2-y1)/(x2-x1)

Answer 3

Insert each point into the formula y = mx + b to get

-10 =-6m + b
-11 = -12m + b

Isolate b in each equation and solve for m

Answer 4

so -10= -6m
-11= -12m

Answer 5

-4.1

Answer 6

Isolate b in both equations to get:

b = 6m - 10
b = 12m - 11

now set b = b to get:
6m - 10 = 12m - 11

Answer 7

Now finish solving for m

Answer 8

subtract 6m from both sides

Answer 9

Let me know what m equals when you're done.

Answer 10

6m+-1

Answer 11

6m=-1 sorry

Answer 12

Subtract 6m from both sides; add 11 to both sides to get

11 - 10 = 12m - 6m

Answer 13

-1/6

Answer 14

11 - 10 = 1
12m - 6m = 6m

Answer 15

You end up with
1 = 6m

Answer 16

then dividing both sides by 6 to get m = ?

Answer 17

so m= -1/6 right?

Answer 18

m = 1/6

I was trying help you realize you made a sign mistake.

Answer 19

Oh I see..don't know why I do that

Answer 20

so the slope is 1/6

Answer 21

If you had it right the first time, I would have told you it was correct.

Answer 22

Anyway, now you know an alternate way to find the slope. Just be careful with the signs.

Answer 23

Thanks a bunch

Answer 24

I use to be so good at this haven't done math in forever

Answer 25

best subject health science and history. Your the best.
