Anotha one DDDDJJJJjjjjjj KHAAALID Another graphing question

He came ;o

Allison:

Lemme try dis first

Hero:

Okay, but ... there is a much easier way than you're probably about to try.

Allison:

https://imgur.com/eKPqki3 How wrong is it?

Hero:

Not gonna say. But erase it.

Allison:

Allison:

Okay now what

Allison:

o.O

Hero:

Whoops, actually, you didn't have that point correct either.

Allison:

Fudge

Hero:

All just ask you two questions: What is y when x is 0? Then what is x when y is -5?

Allison:

Math lovers and experts hate me. My math teacher literally said I am terrible at math yet I have an A- somehow

Allison:

When x is 0, y is 1/3?

Allison:

No lol wait

Allison:

When x is 0, y is -5 and when y is 0, x is 1/3

Allison:

Eh? e.e

Hero:

Actually, when x is 0 y is -5. So that gives (0,-5). We'll go with that. But then, what is y when x = 3?

Allison:

y is 1?

Hero:

\(y = \dfrac{x}{3} - 5\) We can re-write the equation this way. What is y when x = 3?

Allison:

Allison:

Done? Done :D

Hero:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Hero \(y = \dfrac{x}{3} - 5\) We can re-write the equation this way. What is y when x = 3? \(\color{#0cbb34}{\text{End of Quote}}\)

Allison:

1

Allison:

One to the right, 3 up?

Hero:

No, don't do it that way. Insert 3 in place of x, then calculate on the right hand side.

Allison:

https://imgur.com/cT2q9TH Too late e.e

Hero:

It's not too late. Just do it on paper. Literally re-write the equation as I have written it above except in place of x, write 3. Then calculate the right hand side.

Hero:

You should get something such as y = a number

Allison:

Um y=3?

Hero:

How did you get y = 3. Show me your steps.

Allison:

I guessed cause you keep saying y is a number and you keep saying 3 e.e

Hero:

You're not even doing what I asked you to do.

Allison:

Bruh

Hero:

How hard is it to write this: \(y = \dfrac{3}{3} - 5\)

Allison:

Oh y is 1

Allison:

I SAID THAT

Hero:

And then realize that \(\dfrac{3}{3} = 1\) And then finish calculating: \(y = 1 - 5\) What's 1 - 5?

Allison:

Don’t I have it pointed too? e.e

Allison:

4

Hero:

-4 actually y = -4

dude:

This is how I would think about it The equation is written as \(y=mx+b\) m is the slope which is \(\frac{1}{3}\) Slope can also be seen as \(\frac{rise}{run}\) rise is how many points you go up and run is how much you go to the right So we would go 1 up and 3 to the left \(\bf b\) is the y intercept or when x is 0 (Which is the point you have) Basically from that point you are just going up 1 box and right 3 boxes

Allison:

Akdkosjsjajsksksja

Hero:

So the other point is \((3, -4)\)

Allison:

Math is so confusing :-:

Hero:

It's much simpler to plug and play. So your points are \((0,-5)\) and \((3, -4)\)

Allison:

Got it

Hero:

Then after you plot those two points, draw a line through it NOT a line segment

Allison:

Past it???

Allison:

Hero:

You drew a line segment rather than a line.

Allison:

Okay through it c:

dude:

|dw:1526682083593:dw| Another way to look at it maybe it can help

Allison:

https://imgur.com/Bo9UHaq Hot handwriting eh, Hero? o;

Allison:

I have dat Jay

Hero:

Yep, @dude, that's great until you get something like \(y = \dfrac{100}{3}x + 20\)

Allison:

Wuh

Hero:

What are you going to do then? Go up 100?

dude:

Yes but I think she has to get used to the concept first before attempting to do something she doesn't understand |dw:1526682290366:dw|

Allison:

There is no 100, it goes up to 6, Hero •-•

Allison:

OH MY GOD THAT IS SO SATISFYING

Hero:

I'm just saying, plugging in numbers isn't so difficult as I just showed.

dude:

Hero is right, I don't disagree but I think Allison is a visual learner

Hero:

It works for any equation. The rise over run method has limited usage. It's better to work with universal methods. Methods that can work in any linear equation.

Allison:

I am visual hehe. Kid brain.

dude:

There are many visual learners, being one doesn't mean you're a kid e.e

Allison:

Anyway e.e Thank you Avocado c: Thank you JJ c:
