An equation of the form Ax + By + C = 0 is an equation for a straight line?
Where A, B, and C are coefficients. The capital letters represent integer values.
For example in 4x − 6y + 12 = 0 A=4, B= - 6 and C=12
To determine the coefficients we need some background.
A straight line has several general forms
x/a + y/b=1 where a and b are x and y intercepts respectively
or
y=mx + b where m is a slope and b is a y-intercept
As you can see each form presents its convenience for analysis.
Let’s assume we have an equation x/2+y/5=1 then by multiplying both sides by 10 we have 5x + 2y=10 or 5x + 2y – 10=0. In this case A=5, B=2 and C= -10.
I hope that helps

The general equation is
Ax + By + C = 0, where A, B and C are integers and A > 0.

A, B and C are any numbers.
x is the unknown
Thus you solve the equation for x; x = - C/ (A+B)!
SO, given the A. B and C, you find out how much x is!

A ,B ,& C are numbers that u don't kno what they are so u have to figure it out. the letter's represent numbers

2x^2+3x+9=0.......a=2,b=3,c=9..2x^2 mean 2x(square)........
