it's okay :)
so do u know how to calculate the slope using the given ordered pairs?

- anonymous

yes give me a min

- Godlovesme

okiee C:

- anonymous

i dont know bout this answer but it gave me 0.25

- Godlovesme

did u use online calculator?

- anonymous

yep

- Godlovesme

can i show u how to do it without one? :)

- anonymous

sure

- Godlovesme

okiee :))
so we have two ordered pairs (0,2) and (4,3)
ordered pairs are represented as (x,y)
so in this case our Xs are 0 and 4
out Ys are 2 and 3
confusing?

- anonymous

no and ik to subtact both and divide the fraction that come with it

- anonymous

i see what i did

- Godlovesme

what do u mean by "subtract both and divide the fraction that come with it" ?

- anonymous

how i did it was 3-2=1 and 4-0=4 which is 1/4 divid and the answer i goy was 0.25

- Godlovesme

woow smart :D
so are u familiar with the y=mx+b formula?

- anonymous

no not realy

- Godlovesme

okay so
y=mx+b is known as the slope-intercept formula
m represents the slope
b represents the y-intercept

- anonymous

ok so which y are we going to do

- Godlovesme

y-intercept is where the line hits the y-axis
If we put it in an ordered pair form the x MUST be 0
so in this case our y-intercept is?

- anonymous

3

- anonymous

4 im sorry very tired to let you know

- Godlovesme

not quite, the ordered pair should look something like this
(0, y)
and y can be any number but x MUST be 0

- anonymous

so are we just using 0 and 2

- Godlovesme

yes which means the y-intercept is?

- Godlovesme

is X is 0 y is? :P

- Godlovesme

when X **

- Godlovesme

y= 1/4 x + 2 :P

- Godlovesme

@ccf122 hope that helped! :)

- anonymous

thank god for u
