Question

write an equation in the form y=mx+b for the line which passes through the points (0,2) and(4,3)

Answer 1

do u know how to calculate the slope using the given ordered pairs?

Answer 2

@ccf122 u there?

Answer 3

im back sorry

Answer 4

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

Answer 5

yes give me a min

Answer 6

okiee C:

Answer 7

i dont know bout this answer but it gave me 0.25

Answer 8

did u use online calculator?

Answer 9

yep

Answer 10

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

Answer 11

sure

Answer 12

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?

Answer 13

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

Answer 14

i see what i did

Answer 15

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

Answer 16

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

Answer 17

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

Answer 18

no not realy

Answer 19

okay so

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

Answer 20

ok so which y are we going to do

Answer 21

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?

Answer 22

3

Answer 23

4 im sorry very tired to let you know

Answer 24

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

Answer 25

so are we just using 0 and 2

Answer 26

yes which means the y-intercept is?

Answer 27

is X is 0 y is? :P

Answer 28

when X **

Answer 29

y= 1/4 x + 2 :P

Answer 30

@ccf122 hope that helped! :)

Answer 31

thank god for u
