Question

Write the equation of the line that passes through (3,5) and (6,6) in slope-intercept form.
I M P O R T A N T .

Answer 1

Do you know what form is slope-intercept form?

Answer 2

Yes.

Answer 3

do you know how to find slope between two points?

Answer 4

Yes. This Is How Far I Got...

Answer 5

y2-y1 = 6-5 =1
x2-x1 - 6-(3) 3

Answer 6

y=mx+b

Answer 7

So if you have the slope and the form, you've already got the hardest part done. All you have to do now is choose one of your points (say 3,5) and plug in 3 for the x, 5 for the y, and solve for b (the x intercept)

Answer 8

sorry... *y intercept*

Answer 9

I'm Still Confused. :\

Answer 10

Okay, so you start with y=mx+b

Answer 11

you know that m is (1/3), so now you have y=(1/3)x+b

Answer 12

Y=(1/3)X+4

Answer 13

Rakesh Sonai, IKnow That's The Answer But INeed The Work.

Answer 14

So take your equation and a point (any point; it doesn't matter). Let's do (3,5)

Answer 15

sorry, just lost internet connection.

Answer 16

So you know that 3 is your x value and 5 is your y value.
Replace every x in your equation with 3
Replace every y in your equation with 5

Answer 17

Now you have 5=(1/3)(3)+b

solve for b

Answer 18

But Why Am ISupposed To Point It.? First, I'm Supposed To Find The Slop.e Then, I'm Supposed To Choose Either Point And Substitute It Along With The Slope Intercept Form. Last, Solve For B.

Answer 19

Okay. Here's An Example Of How I'm Supposed To Do It.

Answer 20

Umme, I like your free-lance use of capital letters :)

Answer 21

Thanks.

Answer 22

Now Here's The Example.

y2-y1=6-5 1
x2-x1=6-(3) 3

Answer 23

Wait No.

Answer 24

y2-y1=-1-5 = -6
x2-x1-3-(0) = 3 Slope=-2

Answer 25

You said the directions were 1) find slope 2)choose point and substitute it, and 3) solve for b. That's what we did. I don't know what you mean by "point it"

Answer 26

y=mx+b
-1=-2(3)
-1=-6+6

Answer 27

You Said Point It. Nevermind.

Answer 28

So What's The Whole Work.? :\

Answer 29

Sorry; didn't mean to. Other than the point it thing, are you getting the problem or not really?

Answer 30

Umme...?

Answer 31

Yes.IAm.

Answer 32

The Only Part I'm Confused In Is How To Get The 4. :\

Answer 33

That's what you get when you solve for b by plugging in the point

Answer 34

How Though.?

Answer 35

The Last Thing IGot Was,
6=1/3 (6)+b

Answer 36

so you put in a 3 where you see x and a 5 where you see y. The only variable you have left is b, so you solve for b. That will give you 4.
Here-- let me work it out

Answer 37

y=(1/3)x+b

Answer 38

5=(1/3)3+b <---I put in the point for x and y

Answer 39

5=1+b
4=b

Answer 40

So now you take the b (4) and put that where you saw b in the equation

Answer 41

y=(1/3)x+4

Answer 42

Where Did The 5 Come From.?

Answer 43

The 5 is the y value.
Since the point was (3,5),
we know that we'll put a 5 where we see y
and there's a y in the beginning of the equation

Answer 44

Does that make sense?

Answer 45

If that's clear, I'm leaving. Hope this helped :)

Answer 46

this is the much simplier way to do this.
once you findd the slope
plug into the formula and put the equation in point slope form or standards
