Question

find the slope of the line graphed (-5,7) (4,7)

Answer 1

Do you know the slope formula?

Answer 2

To find a slope you need the slope formula.
The slope formula is also called the change in the rise divided by the change in the run, respectively.

Answer 3

i have two choices (a) m= blank or (b) the slope is undefined

Answer 4

you should solve to find out ;)

Answer 5

how do you solve the problem with no formula

Answer 6

Your slope is going to be. 9
Because you do
y2-y1
------
x2-x1

so 7-7 = 0
4-(-5)=9

Answer 7

There's a formula to find the slope if you have two points. As Coda said, you need to divide the change in the rise by the change in the run...or rather, the difference of the y-values divided by the difference of the x-values.

Answer 8

The formula is taken from the rise divided by the run, or y2-y1 / x2-x1.

Answer 9

Okay the formula for finding slope is
\[m=(x _{2}-x _{1})/(y _{2}-y _{1})\]

Answer 10

put the values of x and y and you will get the slope

Answer 12

it is coming undefined as denominator( y2-y1) is coming 0

Answer 13

@MissSosa: Two things. Your answer is wrong, AND you shouldn't be giving an answer at all. Let the person who asked the question solve the problem.

Answer 14

@ProgramGuru: Same thing. Your answer is wrong, and you shouldn't be just giving the answer.

Answer 15

okay @shandelman my mistake. Very sorry!!!

Answer 16

ok is it like this m=(-7-7) (-5-4)

Answer 17

the formula should be \[m=(y _{2}-y _{1})/(x _{2}-x _{1})\]

Answer 18

@shandelman sorry, you make the rules? No, oh okay. BYE. AND UHM I can give answers, is if I like, not a big deal so chill out. K ?

Answer 19

Close. I don't think there's a -7 in either of the points.

Answer 20

-7 is not considered a point. Remember your taking the change in rise over the change in the run going from the second point to the first. So you just have your y2 wrong.

Answer 21

it should be \[m=(7-7)/(4-(-5))=0\]

Answer 22

ok so is that right because i got something different so i guess im still doing it wrong

Answer 23

Remember in the last equation you posted, you had -7-7 for the top, or y2-y1. Your y2 was wrong.

Answer 24

wait if the slope is 0 is it undefined

Answer 25

If you have something divided by 0, then it is undefined.
When you have 0 divided by anything, it is just 0.
So in this case you would have y=0, or just a straight line across a graph.
