Answer 1

What is the formula in finidng slope?

Answer 2

I will have to look that up in my book

Answer 3

y2-y1
-----
x2-x1

Answer 4

Your given points are:
(0,4) or (x1,y1)
(-6,7) or (x2,y2)

Can you plug it in the equation for me?

Answer 5

I am looking through my book it is a pdf so still looking

Answer 6

I listed the equation above:

Answer 9

what do you mean plug it in, I am really terrible at math, so not understanding this

Answer 10

Your given points are:
(0,4) or (x1,y1)
(-6,7) or (x2,y2)

Can you plug it in the equation for me?

Answer 11

well the numbers are (0, -4) and (-6,7) is that what you mean

Answer 12

y2-y1 7 - 4
----- = -------
x2-x1 -6 + 0

Answer 13

Okay I see how you set it up so where do I go from here?

Answer 14

Simplify this:
7 - 4
-----
-6 + 0

-3

Answer 22

@KatrinaKaif , I recommend using the equation editor.

Answer 23

Normally, the negative is in the numerator. So -1/3

Answer 24

Equation editor is that a website?

Answer 25

@Hero will explain.

Answer 26

Nope, it is a button that you click that enables you to create things like this:

\[m = \frac{y_2 - y_1}{x_2 - x_1}\]

Answer 27

wow, very cool. Is that on this page to use?

Answer 28

There is a button named "Equation" underneath the typing box. Click that and see what happens.

If you get the far, copy and paste this into it:

m = frac{y_2 - y_1}{x_2 - x_1}

Then click insert and post.

Answer 29

\[I got \it \] haha and I love it thanks

Answer 30

could not coy and paste though kept clicking off

Answer 31

You have to copy it first, then open the equation editor, then paste. Try it :D

Answer 32

okay

Answer 33

okay when I click insert after copy and paste it goes away

Answer 34

Try it again, except this time, press the space bar once, then wait a few seconds. Make sure you click insert, then click post.

Answer 35

\[m = \frac{y_2 - y_1}{x_2 - x_1} \]

Answer 36

:D

Answer 37

:)

Answer 38

Basically, what I have given you is the format for posting fractions. So now you know how to post those.

Answer 39

Thank you, you are my hero :)

Answer 40

:D I get that a lot, thanks :D

Answer 41

Seriously though, I really appreciate you taking the time to show my how to do that.

Answer 42

No problem :D

Answer 43

I have another problem I was going to try to type in but I don't see the equation editor at the "ask a ?" box

Answer 44

You would have to put it in what's called "Latex" form in order for it to post in that manner.

Answer 45

oh maybe i can type it in here and copy and paste
unless you can help me with the problem?

Answer 46

See your fan testimonial for an explanation.

Answer 47

Okay thank you again hero :)

Answer 48

\[y = -2x ^{2 + 12x - 13} \]
