It’s kind of like whack-a-mole. Whenever you suspend him, he comes back up.

Math is easy to be honest, if you are learning about graphs this is all you need to know:
Point Intercept Form
y=mx+b
y=y point
m=slope
x=x point
b=y intercept
Pretty much if you want to Graph a line, let’s say for example 3=2(5)+2
You would first start with e Y intercept(2) and go up that many up or down from the origin. Then, you take your slope(also 2). Think of the slope as a fraction 2/1. The Numerator is the distance you go up, and the denominator is the distance you go across. If you go up or down doesn’t matter, but the change in x does, becsue it determines the direction of the line(positive, negative, zero slope, no slope). Keep repeating going up(or down) and across and eventually yo will have your line!
Kinds of equations:
Slope Intercept Form:
y=mx+b
This is useful for graphing the line
Point Slope Form:
y+y1=m(x-x1)
This is useful if the problem gives you one point and the slope
Standard Form:
Ax+By=C
Easy to convert into either also lays out your information if you need to find the slope

If you have a line, and you need to find the slope use this easy equation!
y2-y1
____
x2-x1
For example let’s say you have the two points
(2,3)
(3,5)
5-3 =2
__=__
3-2 =1
2
_ is the slope
1
@TheCoders This is Algerbra, so if you aren’t there yet than this will mean nothing to you

Sorry if I nerded out. Also that took so HTML knowledge of invisible characters

#583

I learned this this year, it’s really pretty easy when you get the hang of it!

#584

Ooh hoo! Looking good!
I’m a math nerdy pants, too

I’m sure you’d love the Numberphile Channel on YouTube

#585

MmmHmm.

You can do HTML awesome! I am self teaching myself.

Math is really easy! It’s fun too!

#586

Woo honors algebra, (which is what I am in) but strangely I learned that last year lol

#587

im like three years ahead in maths help

just wait for exponential and quadratic and

Hey, @HopscotchRemixer! If you didn’t already know, I’m taking a year long break from the Forum and I’m only coming back monthly to clean-up (it’s Australia Day so I came a little early).

I’d like to be removed from your tag list so that I’m not tagged on posts I won’t read.

Is this possible? I can’t seem to do it myself.

Thanks.

#589

Ok I will remove you!

#590

Wait that was algebra

#591

Yeah it is Algerbra …

#592

Ok…

#593

Ah, ok. Which grade would you learn this in?

#594

I learned it in 7th grade(because I am in gifted math) but most people learn it in 8th grade and some people learn it in 9th grade.

#595

I wish my school had advanced classes. My old school did, but this is a private school with super small classes. I guess I’ll learn that in a few years.

#596

I am glad I didn’t fail my mid term

#597

algebra 1 is usually ninth grade i think

but ye im in it yay

#598

You sure?

I’m in eighth with Algebra 1

It’s pretty easy?

#599

idk
