This is one of the questions I had trouble with. When converting from slope y int from to general form, I would get the numbers correct, but half the time the negatives and positives would be reversed. this is because when writing an equation in general form (Ax+By+C=0), I did not know the ”A” had to be positive.

here is the wrong answer,

here is the correct answer,

What I do now when converting to general form, is if the Ax part of the equation is negative, I move it to the other side and inverse it along with the C, If it is positive, I leave it where it is and move the Y to the other side of the equation and inverse that.
