the slope of a line is y2 -y1 / x2 -x1 i will pick x1 = 0 and x2 = 2
The slope becomes -2 - (-2) / 2-0 = 0/2= 0 zero slope which is answer d.

huh

the answer is d

ok thanks

- dakid88

welcome can i have a medal

Zero Slope

- dakid88

wht

- anonymous

so which one

- dakid88

d

- FireKat97

B

- dakid88

it is d

- dakid88

@pinklion23

- anonymous

why is it d or b?

- dakid88

@mbma526

- dakid88

d

- FireKat97

|dw:1443791275677:dw| an undefined slope looks like this

- dakid88

no it dont firekate

- anonymous

Its zero Slpoe I promise!!!

- FireKat97

sorry thats the x axis being cut off in my diagram :/

- dakid88

@triciaal

- anonymous

ok well im even more confused now

- dakid88

|dw:1443791449704:dw|

- dakid88

|dw:1443791525618:dw|

- FireKat97

its zero, I'm not too sure how I can explain this properly, but for horizontal lines, the slope is always zero

- anonymous

Dude just stop your only saying D so you can get the stupid medal but at this point idc about it I just want him to get the right answer!

- Nnesha

formula to find slope \[\huge\rm \frac{ y_2-y_1}{ x_2-x_1 }\]
since the line is horizontal |dw:1443791506934:dw|
horizontal line when y is constant and x values are changing

- dakid88

u dont tell me wht to do redneckk and me too

- Nnesha

let's say we have (2,3)(4, 3)( notice y values are the same )
plugin \[\frac{ 3-3 }{ 4-2 }\]
when you subtract same numbers what would you get
in this question 3-3 =?

- Nnesha

remember the formula is = change in y's over change in x's

- anonymous

ok so im going with zero slope
thank you everyone
i'll tell you who's right a bit later and medal them

- Nnesha

did you understand ???

- anonymous

yeah a bit
that helps with the rest of the questions i might have thank you

- Nnesha

alright just practice
remember when we subtract same numbers we will get zero
so zero divided by anything would be just 0

- anonymous

ok got it :)

- Nnesha

let's say if we have vertical line |dw:1443791845577:dw|
in this questions x value would stay the same

- Nnesha

so when substitute points into the formula (3,2)(3,4) (x values would be the same ) \[\frac{ 4-2 }{ 3-3 }= ???\]

- Nnesha

i'm pretty sure ur next question would be on vertical line slope

- anonymous

yeah it is

- Nnesha

alright so \(\color{blue}{\text{Originally Posted by}}\) @Nnesha

\(\color{blue}{\text{End of Quote}}\)
solve this

- anonymous

2/0

- Nnesha

i just picked two points but for vertical line x -coordinate would be the same 4sure

- Nnesha

right so answer would be what
2/0 = ?

- anonymous

0
so zero slope?

- Nnesha

no no you can't divide by zero
whenever u get `0 at the denominator ` answer would be undefined bec you can't divide by 0

- anonymous

oh undefined ok bc thats what i originally thought

- dakid88

i told u

- anonymous

i knew there was some rule between the horizontal or vertical slope i just forgot which

- anonymous

@dakid88 we're on a different question so actually, you're wrong

- dakid88

oh my bad

- anonymous

its all right i understand it now
