it isnt tho

wait

its linear right

bruh this is so simple xD y am i so stupid

@BunkerHermit let me go look at my old algebra work.

nah its fine

u dont have 2

@BunkerHermit You sure? I’m taking geometry this year and Algbera 2 next year, so it is sort of a helpful to me to rewiew it. Unless you have the answer, but I don’t mind is what I’m saying

its fine im just doin some review

i just forgot

im in 8th grade so i needed to review this stuff bc they r teaching it and i forgot but im teaching myself calculus so it was a win win because i forgot some stuff

@BunkerHermit Ok! Just one thing about functions- the best way to tell if something is a function is by graphing it and seeing if it passes the vertical line test- if you can draw a vertical line on the graph without it going through two points, since that would mean x has two y values. Let me send just one picture because I’m a little excited (I forgot this). Also I’m in eighth grade too so cool

yea ik

thx for da advice tho

Oh ok lol 😂 I’m just glad I learned something from algebra. That class was... not my favorite

I sent the image so then if anyone else needs it they have it btw since it’s a handy little trick

To tel if it is a function or not, just see if there are 2 points where the x is the same but the y is different

Vertical line test

That is not a vertical line.

That is a straight line with a slope of 0.

Haha <:thinking:726878987837636698>

If slope is 0. Then it's horizontal <:thinking:726878987837636698>

isn't the slope 0 when it's horixontial and undefined if it's vertical

@2Lazy2BeOriginal Yes. I actually forgot that so I’m glad this became a discussion lol.

I mean when the hell are you gonna use that?

That’s me alllll the time in school

That is linear I think

It’s y=5

Linear is like a straight line

Wait nvm idk I’d it is

If

the slope is 0 because it's horzontial

Linear

You're right

Linear if y can be expressed as a simple multiple of x plus some constant. In this case it's 0*x + 5

Yes

Y=mx+b if x = 0 and b = 5

that simplifys to y = 5

Exacrly

idk how to use algebra to prove a vertical line though

@2Lazy2BeOriginal I it is because you can’t calculate m (the slope) so it all gets screwed up. If you have to prove it, then you would use that formula that calculates slope, y2 - y1 over x2 - x1. Then it’ll always end up as some y value over zero, since the x values are equivalent to each other and when subtracted will always make zero, and any number over zero is undefined since you cannot divide by zero.
