What is the slope of the line between (–4, 4) and (–1, –2)?

Question

aripotta · Answer

slope formula:

aripotta · Answer

do you know what to do?

anonymous · Answer

no lol

aripotta · Answer

see where it says y2 and y1?

aripotta · Answer

that's the y part of the coordinates

anonymous · Answer

Okay, (-4,4) is a coordinate. Do you know which one is x and which is y?

anonymous · Answer

Yes -4 is x
and 4 is y i think..

aripotta · Answer

that's right

aripotta · Answer

so if 4 is y1, then what's y2?

anonymous · Answer

-1 & -2

aripotta · Answer

no..

aripotta · Answer

the second coordinate is (-1,-2), right?

aripotta · Answer

what's the y part of that coordinate?

anonymous · Answer

yea wouldnt that be x i and 2

anonymous · Answer

Okay, if -4 is $$x _{1}$$ and 4 is $$y _{1}$$
What is  $$x _{2}$$

And what is $$y_{2}$$

anonymous · Answer

x2= -1
y2=-2

aripotta · Answer

that's right, so draw for me what the formula would look like with the numbers put in

anonymous · Answer

Yep!

Okay so look at the attachment that @AriPotta put in. It's the slope formula. Plug in x1, y1, x2, and y2, into the formula.

anonymous · Answer

-4 x 4/ -1 x -2

aripotta · Answer

it wouldn't be multiplication, you're subtracting. and it has to be y2 - y1/x2 - x1

aripotta · Answer

do you see what i'm trying to say? :/

anonymous · Answer

lol yea i see hold on ill tell u the anwser...

anonymous · Answer

i got 2.66666 i dont think i was right lol

aripotta · Answer

how did you get that? can you show me?

anonymous · Answer

-4-4= -8
-1-2= -3
Divide -8 by -3= 2.666666666

aripotta · Answer

you have to subtract the y1 from y2. you're subtracting y1 from x1. the two y's are on the top and the two x's are on the bottom
