Question

Write the slope intercept equation for the line containing the given pair of points..(-3,4) and (3,1).... Please HELP ME ANYONE

Answer 1

1. Find Slope
2. Use Point-Slope Formula
3. Simplify

Answer 2

I dont know the formula

Answer 3

slope = m
m= (y2-y1)/(x2-x1)

Answer 4

yep, than plug m in:

y-y1= m(x-x1) to find eq.....

Answer 5

can you show me where each number goes and I will do the rest I get confused with which is the y-y1 and the x-x1.

Answer 6

Trust, it must still be early where you're at.

Answer 7

Usa,

Answer 8

I live in the carolinas

Answer 9

Then that means it's very early.

Answer 10

and very late

Answer 11

like 3am here where you at in the world. and what is the time there

Answer 12

x1 and y1 is from one of your two given points. (-3,4) = (x1,y1) & (3,1)= (x2,y2). What did u get for slope m?

Answer 13

yes 1/2 but where do I go next

Answer 14

You should get -1/2 for m...?

Answer 15

Late as ever.

Answer 16

i did what is next

Answer 17

Now, use eq:
y-y1=m(x-x1) to find slope eq.

Answer 18

You could use either points, both will give u the same answer.

Answer 19

ok how do i start

Answer 20

Just plug in y1 and x1 in the eq. and solve using algebra.

Answer 21

so -3=-1/2(4)+b

Answer 22

I believe you using the other eq. "y=mx+b"
b is your y-intercept on the graph (if u graphed it). You are not trying to find b but instead an equation of a line in that form.

Use this my friend:
y-y1= m(x-x1)
* You know m
* You know y1, x1
* Plug and chug.

Answer 23

so it would be 5=1/2(6)

Answer 24

3=1/2(6)

Answer 25

Uhmm, not quite:

y-y1= m(x-x1)
Lets do the first point: (-3,4) ---> (x1, y1)
Plug in what u know: y1= 4, x1=-3, m=-1/2
y-4= (-1/2)(x-(-3))
From here, solve...

Answer 26

um -4=-1-1... i dont know I hate math. ugh

Answer 27

will you please write out everything foe me i am already gonna give you the medal please with cherries on top.

Answer 28

you dont do anything with y and x. at the end, u should have something like y= ?x + ?

Answer 29

i will simplify u one more step to see if u could finish it by yourself:
y-4= (-1/2)(x-(-3))
y-4=-.5x -1.5

easier now? solve

Answer 30

oh I think I got it now y=1/2x+5/2

Answer 31

yes cept your slope (m) is -.5.
if u plug in the other point, you will have the same answer.
your 5/2 is your y intercept. if u wanna see, plug 0 for x.

Answer 32

o okay is now
thank you

Answer 33

your welcome. bye bye

Answer 34

bye
