Why are you still not flexible enough to use the form that's appropriate for the given information?

It's like you missed the whole point of the pic you attached.

>>8561254
Why are you not using superior vector form?:

(x,y) = td + c

where d is the direction vector, c is the position vector of one point on the line, and t is a real parameter?

Because General Form also covers vectors.

>Because General Form also covers vectors.

No it doesn't. The general form doesn't have the concept of "t", which indicates how many displacement vectors d you are away from the starting point c. Basically, t gives you a customizable coordinate expressed in units of d. For example, in physics, you can define the vector d to be 1 cm in length, which allows you to easily use t as a measurement of the location of a point along the line in cm units.

In the vector form, c and d and t all actually MEAN something useful.

In the general form, the only way to extract any meaning from a, b, and c is to calculate expressions like -(a/b) and -(c/a) and -(c/b). The general form is a standard form for algebra, but you pay a price for that because the constants don't have much useful meaning on their own.

A and B are the coordinates of the vector that passes through the line you mong.

>a single straight line

who cares, this is literally babby shit

just use y=mx+b, manipulate as needed

>>8561254
Just because it took you until junior year to learn this concept does not make it challenging or important.
