Question

What is the equation of the line which includes points (0,3) and (4,5)?

Answer 1

replace variables by order pair (x , y)
first number in order pair is x 2nd one is y
if both side equal then that order pair is ur right answer :-)
remember: you should substitute both order pair values and both one should give you the equal sides

Answer 2

I had 2 1/2. I don't think it's correct, though.

Answer 3

where are the equations ??
and plz show your work :-)

Answer 4

wait do you have the equations ??

Answer 5

okay got it first you have to find slope :)

Answer 6

I put it as 0 - 4 / 3 -5.

Answer 7

It's a bit longer, I have to find the paper first.

Answer 8

wait what is the formula to find slope ?

Answer 9

\[\huge\rm m = \frac{ y_2 - y_1 }{ x_2 - x_1}\]
x should be at the denominator and y at the numerator

Answer 10

Okay, so it should be a bit different.

Answer 11

just flip the fraction

Answer 12

So 5-3 / 4 - 0?

Answer 13

there you go

Answer 14

solve that

Answer 15

And now I have to divide it?

Answer 16

bec its slope which is \[\rm \frac{ rise }{ run }\]
so keep that in fraction form

Answer 17

2/4 was what I got.

Answer 18

yep reduce that fraction

Answer 19

So the answer is 1/2?

Answer 20

yep not the answer just slope is 1/2
what's slope intercept form equation ??
do you know ?

Answer 21

Could you refresh my memory, please?

Answer 22

okay
\[\huge\rm y = mx +b\]slope intercept form equation where m is slope nad b is y-intercept
y intercept on y -axis when x =0
when x =0 y = something <---this would be yoru y-intercept

Answer 23

So I should put 1 into Y and 2 into x.

Answer 24

m is slope which is always with x
m = 1/2 so just replace m by 1/2

Answer 25

Oh, so it should be Y = 1/2x + B, then.

Answer 26

yep that's right
now you can use one of your order pair
where (x,y) first one is x and 2nd number is y plug that into the equation to find b(y-intercept )
but for this question you don't have to solve
bec like i said
y-intercept when x = 0

Answer 27

Uh...so which would be the best choice, 0,3 or 4,5?

Answer 28

when x =0 y = ??

Answer 29

Y is three.

Answer 30

so b =3

Answer 31

Y = 1/2x + 3.

Answer 32

Although I don't think it's finished.

Answer 33

yep done!

Answer 34

done! that is equation in slope intercept form

Answer 35

the*

Answer 36

That's it? That's the answer?

Answer 37

I didn't know it was so simple.

Answer 38

yep simple stuff lo_Oks hard

Answer 39

So my answer is going to be Y= 1/2 x + 3.

Answer 40

Thank you. I'll close this one now.

Answer 41

yep that's right :)
