Question

Find the equation of the line that passes through the pair of points. Write your answer in slope-intercept form.
(5, -6\), (-5, 0\)

Answer 1

do i do the y2-y1/x2-x1 ?

Answer 2

yes, that's the first step.

Answer 3

That will give you the slope

Answer 4

ok brb 30 seconds. im gonna do that first

Answer 5

-6?

Answer 6

-0.6

Answer 7

dude your making me lag really bad when you do that rofl

Answer 8

y=mx+b the "m" is what you are solving for with the slope, the "b" is the y-intercept

Answer 9

saifoo, go help some junior high kids

Answer 10

why the heck is that? o_O

Answer 11

i had 0-6/-5-5. ws that wrong?

Answer 12

Because your spamming

Answer 13

Just chill

Answer 14

1 sec on the slope

Answer 15

\[\Huge \frac{0+6}{-5-5}= \frac{6}{-10}=-0.6\]

Answer 16

ya saifoo is right

Answer 17

I actually did this stuff like 6 years ago so I'm not the most fresh on it, sean knows what hes doing, listen to him.

Answer 18

but the equation has -6. take another look at it

Answer 19

(0-(-6))/(-5-5) is the slope intercept formula. This is your m in the equation y=mx+b. The b is your y-intercept. After you solve for m, you can plug in either set of (x,y) values and get your b.
Hope this helps!

Answer 20

where is that equation u r talking about? @dude.

Answer 21

its 0 - (-6) subtracting a negative gives a positive value

Answer 22

ah. ok. derp

Answer 23

Sean do you know laplace transforms at all?

Answer 24

So your answer would be y = -6/10x + b.
If you want b, then you would have: 0 = -6/10(-5)+b
Which evaluates to:
0 = 30/10 + b
0 = 3 + b
-3 = b
So final equation is: y = -6/10x - 3

Answer 25

@Pan, no. Unfortunately, I am a computer science major and Diff Eq is not required, but I am taking next term. :(

Answer 26

Ah ok, no worries

Answer 27

At least you know what it is, better than I could say before I took DEQ

Answer 28

I only know because I have many friends who are math profs. Hear that they are EXTREMELY useful though. Has something to do with integrals right? if you like, go ahead and like Tutor Sean on Facebook. I could use someone on there who knows Diff Eq if you are interested. It is another community where I help people solve math problems. I could make you an admin so that you can answer questions. :)
