Question

Okay, I think I already did the- No I didn't, the answer for the first one is 1/2 I think or that's part of the answer, TSO helped me get the finale outcome but now I need to put it in slope intercept form.

Answer 1

Slope intercept is y=mx+b (we know this pls)
(There are a couple ways to solve this)

We know the slope is 1/2
So

\(\large y=\frac12x+b\)

In order to find b, we just need to substitute one of the points they gave us

Answer 2

one of them? So I can just pick any o.o

Answer 3

Yes

Answer 4

Either (8,9) or (-2,4)

Answer 5

Let's do uhm... (-2,4) I guess

Answer 6

Okay so we substitute the x and y coordinate into its corresponding variable
x= -2
y= 4

\(\large 4=\frac12(-2)+b\)

Now we can solve for b

Answer 7

Alright, let me process LOL

Answer 8

D:

The point is in (x,y) form, right?

Just substitute the x coordinate in for x and y the for the y

(-2,4)
( x, y)

Answer 9

4 = 1/2(-2) + 4
??????????????????????????????????????????????

Answer 10

No no b is what we are solving for

\(\large 4=\frac12(-2)+b\)

Do \(\frac12\times \)-2

Answer 11

-1

Answer 12

Yes so we have

\(4=-1+b\)

We are trying to isolate b

What is the opposite of subtracting 1?

Answer 13

pSh if I get this wrong I'll be disappointed in myself adding

Answer 14

Good good c:

Answer 15

Now add 1 on both sides

Answer 16

Oh YEAH cuz we do that, yeah yeah ok

Answer 17

5 and 1, if I added on the right sides

Answer 18

WOT

Answer 19

D:

Add 1 on both sides, you are trying to get rid of the -1

-1+1=0

4+1 =5

So, 5 = b

Answer 20

It was blank

Answer 21

Oh rip

Answer 22

Oh I said 1 OOP

Answer 23

Its okay xD

Answer 24

Boom, 5 and 0 is what I MEANT so that means we do like... (5,0).........or

Answer 25

Well uh 5 and b, i had written it down already but yes

Now that we have b, we just put it into the equation we made

\(\large y=\frac12x+b\)

Answer 26

uhm.... \[4=\frac{ 1}{ 2 }(5) + 1\]

Answer 27

I forgot where the five goes

Answer 28

No no we're just putting in the b value

Remember from our last part
5=b

Answer 29

le sigh

Answer 30

I didn't explain it well, that's on me

Answer 31

I'm just me as usual, UHM, so b = 5 so it's gonna be \[4=\frac{ 1 }{ 2 }x + 5\]

Answer 32

x and y are just iteself now

We only substituted the point just to get b, but now that we know what it is we dont need them there

\(\large y=\frac12x+5\) is your answer

Answer 33

Recap:

Slope intercept is y=mx+b

We know the slope is 1/2 [from Q 1]

\(\bf \large y=\frac12x+b\)

In order to find b, we just need to substitute one of the points
================================================

We chose (-2,4)
Okay so we substitute the x and y coordinate into its corresponding variable
x= -2
y= 4

\(\large 4=\frac12(−2)+b\)

Now we can solve for b
[First multiply \(\frac12\) and-2]
\(\large 4=-1+b\)

[Now add 1 on both sides to get b by itself]

\(5=b\)
================================================

Now that we know what b is, we substitute that into our original equation
\(\large y=\frac12x+b\)

\(\large \boxed{y=\frac12x+5}\)

Answer 34

I was like; ohhhhh frickkkkk I have to read all disssss?!: And then I look up there and it says "Recap" I'm like PHEW! But ye basically that's it, so the answer-- does or doesn't end at y = 1/2x + 5 ?

Answer 35

I think it does..

Answer 36

/makes recap 50x larger


Yes that is the answer, we're done with the Q xD

Answer 37

xD So the ANSWER for question 1 is 1/2 and the ANSWER for question 2 is y = 1/2x + 5 basically

Answer 38

Uhh for #1, TSO helped you get the answer

We only did #2

Answer 39

Yep yep, got it tho I'ma just *closes post and writes the recap so I can TRY to do it myself next time*
