Question

3x+9=0 , Find the slope of the graph of each equation, show work please. need help i'm confused

Answer 1

first you need to put it into slope-intercept form (make sure the formula is correct here)

Answer 2

is that a 0 or a y?

Answer 3

yeah, it's usually a y

Answer 4

its a zero , but i suppose it could be a y

Answer 5

odd

Answer 6

Then I guess, we have a special case!

Answer 7

are you sure you arn't solving for x?

Answer 8

nope

Answer 9

you may need to do so

Answer 10

well suppose you need to, what's x=?

Answer 11

because that is a graph

Answer 12

it would be 3

Answer 13

so, is x vertical or horizontal?

Answer 14

Close, -3

Answer 15

oh, yeah, sorry. it is -3

Answer 16

it does't say if horizontal or vertical

Answer 17

Just know that when graphing x or y, it's either a vertical or horizontal line, respectively

Answer 18

There also is only one intercept, btw

Answer 19

so at, for instance, y=6, it's a horizontal line at 6 up from the origin

Answer 20

and at x=6, it's a vertical line, 6 right from the origin on the x axix

Answer 21

i know but all it gives me is that equation 3x+9=0 and to find slope without a graph or nothing

Answer 22

Well, there is only one intercept, x=-3, which we solved earlier..

Answer 23

ok, all you need to know is that vertical lines are undefined, and hor. lines are 0.

Answer 24

And with all two dimensional lines usually have TWO

Answer 25

so either m=0 or "undefined"

Answer 26

So, this one clearly is one-dimensional

Answer 27

yea i think it is

Answer 28

On the x-axis, so a straight line up and down, and since slope is rise over run, rise being, (let's choose a random point) 4, the run, would obviously be 0. You can't divide by 0, so its undefined.

Answer 29

aptly stated homework

Answer 30

yea

Answer 31

so i guesses its undefined

Answer 32

yep. 0/anything = undefined

Answer 33

when refering to slope, that is

Answer 34

yea thats true

Answer 35

thank you very much both of u guys, i appreciate it

Answer 36

welcome! any more questions?

Answer 37

no im good , thanks again
