I think the first one may actually be 1/2 but I am not sure...

pooja195 · Answer

well you need to get it in y=mx+b form so you have to subtract 2x what do you get?

pooja195 · Answer

do you know?

inexilewetrust · Answer

I don't know where to subtract 2x. I just went over this in my last post but I can't retain mathematical concepts. I am not sure why, I just do. I can explain chemical reactions, DNA replication processes. But I can't do as something simple as find a line and put it in slope intercept form.

when you move something from one side of the equation to another, you change the sign
since 2x is positive, it will be -2x since you move it on the other side

Okay, how would I know (when I am doing some problems on my own) if my answer is correct?
