Yeah... over here too... Line stuff was wayyy back.

"Ax+By+C=0 is the way to go"
eeaeeae, I hate standard notation - y = mx + b is much easier IMO. In my grade 9 math class we did like grade 10/11 stuff . I guess that's why I got a 70% even though I sortof consider myself good in math...

y=mx+b to standard form really isn't that complex...

It's just moving things to one side, and equating to zero.

Then there's some funky rules like... a can't be negative or something.

No decimals either.

Idealy, just mulyiply the entire thing by the "run" of m, then isolate for zero, if a is negative then multiply through a negative, and you're done.

Yes I like y-intercept form better too,
and A cant be 0 thats also valid
but what do u mean it cant be a decimal
