Also, michael, you're a retard. Honestly, you're unbelievably fucking stupid. This is like the beginning of Algebra 1. I can't even explain how fucking stupid you must be to not be able to figure this out on your own.
You add 3x to both sides, so it's 3x+y=9 |
Im 13 and do not pay attention in algebra, of course im stupid.
Will +rep now, i cant believe i didnt see that. | Right, +rep lubenow, not Arcane. |
Didnt want it solved, i wanted it solved and an explanation on how to do it. |

Edit - 3x+y=9 is the standard for that equation. Unless your teacher wants 3x+y+9=0 or something. Forgot which is which. |
EDIT: Oh, you needed it explained. | Except Arcane's equation is wrong. He just did it quickly and accidentally forgot to flip the -3x to +3x.
Micheal, not paying attention in algebra is no excuse. Honestly, answer Jake's question, are you in 6th grade Algebra?

Okay, so standard equation of a line is
ax + by = c
-3x + 9 = y
Subtract 9 from both sides to isolate the x variable (You could also add 3x to both sides, but for the sake of sticking to the mold I am doing it this way)
-3x - y = -9
Multiply both sides by -1 to remove negatives
3x + y = 9
Bam. |
You missed Elpacco already explaining it
Also, haow to take two given points alone and transfer into Standard Form |
Use the two points to calculate the slope (Change in rise over change in run, i.e. (Y1 - Y2/X1 - X2), and plug in any of the coordinates to slope-intercept form to calculate the y-intercept (If it's not given)
Then convert the slope-intercept form to standard. |
You mean Y2-Y1/X2-X1. |
There's no difference
(8,4) (5,3)
4-3/8-5
1/3
3-4/5-8
-1/-3
1/3 |
I guess you can put it that way, since slope is Δy/Δx, but nobody writes it as Y1-Y2/X1-X2 simply because in math, you want to get the answer as directly as possible. Having to go through the process of eliminating the negatives, even though it's fast, is not the most direct way.
As my teacher would say, mathematicians are lazy people, you get the answer as fast as you can, with as little confusion in there as possible.
@Elpacco - the equation is not wrong. That's a hyphen and not a negative sign. I always put negative/subtract signs right next to the number without the space.

Eh, I thought the space would have made it clear, but I guess not. I'll keep that in mind.

Slope is d[y(x)]/dx, or y'(x) in short form.
