Question

Please help ive tried eveything
find the sloe of the line

(-16,6) (-18,-10)

Answer 1

Slope
Take the coordinates \((x_1,y_1)\) and \((x_2,y_2)\)
Slope formula is
\[Slope=\frac{y_2-y_1}{x_2-x_1}\]
Substitute and find slope

Answer 2

@Talyababyy , are you having any problem in understanding the above mentioned method? If not then please let us know whether you get it or not.

Answer 3

I dont understand anything

Answer 4

ok! no problem. I will try my best to teach you this part.

I have two points : \((-16,6) \quad\& \quad (-18,-10) \)

Right?

Answer 5

yes

Answer 6

Now as we know that if we have two points as : \(x_1 , y_1\) \(\&\) \(x_2 , y_2\) then :

\(\textbf{slope} = \cfrac{y_2 - y_1}{x_2 - x_1}\)

So here I have two points as : \((-16,6)\) \(\&\) \((-18,-10)\)

that is \(x_1 = -16\) , \(y_1 = 6\) and \(x_2 = -18\) and \(y_2 = -10\)

Now put these values of \(x_1 , y_1 , x_2 , y_2\) in the equation for slope :

\(\textbf{slope} = \cfrac{y_2 - y_1}{x_2 - x_1}\)

\(\implies \textbf{slope} = \cfrac{-10 - 6}{ -18 - (-16)} \)

Answer 7

Let me know, if you get any problem in understanding the above method.

Answer 8

so would the slope be
(-18,16)

Answer 9

No! can you tell me what is \(-10-6 \) ?

Answer 10

????

Answer 11

See, I have : \(slope = \cfrac{-10-6}{-18-(-16)}\) , right?

Answer 12

yes i guess

Answer 13

Now solve for numerator first : \(-10 - 6\) , what is : -10 - 6 ?

Answer 14

subtract

Answer 15

Well, I think you're having problem in solving this . Let me make it easy :

\(slope = \cfrac{-(10+6)}{-18 + 16 } \)

Now, what is 10 + 6?

Answer 16

16

Answer 17

good, so I have : \(\cfrac{-(10+6)}{-18+16} = \cfrac{-16}{-18 + 16}\)

Can you tell me what is : - 18 + 16 = ?

Answer 18

-2

Answer 19

how patient the helper is, i give you the formula to find slope and the image to express it
