i_love_my_nieces · Answer

The x- coordinates are the -3's right?

anonymous · Answer

unidentified

luigi0210 · Answer

$$\LARGE m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$$ 
And yea, the -3's.

luigi plz help me

solomonzelman · Answer

cgoel, you are giving out the answers, and the wrong ones !

i_love_my_nieces · Answer

$$-3 - -3 = 0$$

solomonzelman · Answer

Yes

luigi0210 · Answer

Right, and what can't you have in the denominator?

i_love_my_nieces · Answer

Huh?

solomonzelman · Answer

your denominator in a slope formula is equal to what ?

luigi0210 · Answer

There is a restriction on the denominators.

anonymous · Answer

could you guys come to my question after u finish up with this one?

i_love_my_nieces · Answer

I don't know how to find that. @Luigi0210

luigi0210 · Answer

It can't equal 0.

solomonzelman · Answer

$\Huge\color{blue}{ \bf     m= \frac{y_1-y_2}{x_1-x_2}	 }$

$\Huge\color{blue}{ \bf     m= \frac{(-5)-(-6)}{(-3)-(-3)}	 }$

also

$\LARGE\color{blue}{ \bf     \frac{x}{0}=undefined	 }$    for any value of x.

i_love_my_nieces · Answer

I think my answer is Undefined.

solomonzelman · Answer

Yes, you are thinking correctly. And as I see, you already know why :)

i_love_my_nieces · Answer

Yes sir. Thank you.

solomonzelman · Answer

using the slope formula, you can always prove that 

slope of horizontal line = 0
slope of vertical line = undefined  (in other words, it has no slope)

I'm not a sir... but..... YOU WELCOME !
