okay well i have some algebra homework to do and there are a couple things that have me confused. you see, in this section of our book we are finding slope and y-intercepts, as well as graphing them. i could do just fine if they're already in slope-intercept form, but im having trouble changing a few of them. for example:
this is easy, as the slope is right there. slope is 3. and y-intercept is 1. and some problems like this:
i could put that into slope intercept form without major complications.
the -9x and the +9x cancel eachother out, and you have to do the same thing to the other side. so it's now changed to:
because the 0 is understood in that. so slope is 9 and intercept is 0 or the origin. but im kind of lost for a couple of these:
for the first one, im not sure if you would want to:
(i also dont know if you'd write it as 4y=3x-16 or 4y=16-3x)
or if you'd want to:
in this, the four would cancel out on the y side and just divide as usual on the other side, making it:
and then you'd subtract the 3x on both sides.
or does that order even matter?
and on the other one:
im just lost on that one. i tried looking back in the book and i can't really find any help for those.
so is there anybody out there who could tell me what exactly to do in these problems? thanks!
