I'm having some trouble with this problem in my test review. Here it is:
Find the equation of each line in standard form (where A > or = 0, and A, B, and C are integers):
Slope is (c/d), contains (a, b)
This was in a group of problems, and I didn't have any trouble with the others (they all had numbers instead of variables). To start this one, I put it into point-slope form like I had with the others.
So I had: y - b = (c/d) * (x - a)
y - b = (cx/d) - (ac/d)
y = (cx/d) - (ac/d) + b
I'm at a loss as to how I can put this (if it's even correct so far ) into the standard form. I checked the key and the final answer should be cx - dy = ac - bc. Any help on how to get there would be much appreciated! Thanks. Let me know if anything I wrote was unclear
