The standard form of a linear equation is Ax+By=C
It is most of the time also stated that A must be positive and A, B and C should all be integers.

y=x+3
You can subtract x from both sides, so you get:
y−x=3
This is sometimes regarded as the standard form, but most of the time, you need to make sure that A is positive, and it is currently −1. How can we change a negative number to a positive number: we multiply by −1. Also, whatever you do at the left part, you must also do at the right part:
- 1 ( y - x ) = - 1 3
−y+x=−3
After some reordering you get:
x−y=−3

I have a representation of a linear equation in standard form (ax+by+c=0) which I am representing as a set of coefficients: a,b,c.
I want to normalize these so that any two equations that represent the same line can be compared programatically to see if they're equal just using the co-efficients. For this I need the co-efficients of any two equations representing the same line to be equivalent after normalizing.
I normalized the values by dividing all coefficients by a2+b2+c2 which scales the coefficients to be the same but I don't know how to account for sign changes in this.
For example, if I have equations: 2x+-4y+2=0 (represented as 2, -4, 2) and -2x+4y+-2=0 (represented as -2, 4, -2), how can I transform the coefficients to make them equal?

I have been learning that the standard expression of a linear equation in two variables is of the form:
ax+by+c=0 while a0 and b0. I want to understand the purpose of the constant 'c' in this equation and where it was derived from, whether it be graphically or algebraically.

Given a linear equation pass through the point(6,4) and two axes, and formed a triangle with area 6. I want to find the equation of that line.
My attempt is letting the equation be y4x6=m. Then using the fact that the area of triangle is 6, forming the equation 12baseheight=6. I got the base and height of the triangle from the axes, base=64m and height=46m
Then substitute the equation 12baseheight=6 and get 36m236m+16=0 which leads to no solution. Can anyone let me know what's wrong?
