Question

Write an EQUATION for the line that passes THROUGH the points (0, -6) and (-3, 0).

a:y= -2x- 6
b:y= -2x- 3
c:y= -1/2x - 6
d:y= -1/2x - 3

@KeganMoore @Nurali @waterineyes @ganeshie8 help?

Answer 3

Use two point slope form..

Answer 4

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

Answer 5

Just plug in the values there..

Answer 6

please someone explain me whats slope i'm completely lost!

Answer 7

\[x_1 = 0, x_2 = -3\]
\[y_1 = -6, y_2 = 0\]

Answer 8

\[Slope = \frac{Difference \; \; of \; \; y \;\;coordinates}{Difference \;\;of \;\; x \;\;coordinates}\]

Answer 9

ok

Answer 10

...

Answer 11

Here, can you find slope??

Answer 12

Firstly tell me what is the difference of y coordinates there?

Answer 13

I think so

Answer 14

-6?

Answer 15

So, after finding slope write here, then we will guide you further..

Answer 16

See, you have done -6 - 0 to get -6.

In the same way you will find difference of x coordinates.

Answer 17

x = -3
y = -6
?

Answer 18

the difference...

Answer 19

What is difference of x one??

Answer 20

I mean what you got for difference of x coordinate?

Answer 21

it's -3?

Answer 22

0 - (-3) = ??

Answer 23

so it's "c"

Answer 24

Why it can't be d??

Answer 25

"c" is pretty good..

Answer 26

u think it's d or c
u know this better then I do

Answer 27

Ha ha ha..

I think none..

You said "c", so I just asked you why it can't be d? (may be you will be guessing also)..


Then, I check which one it is, then I found c..

Answer 28

Answer part matters to you not me, I want to give just the method of finding it.. :)

Answer 29

ok! Thanks
