Re: equation of the line

Hi mom;

You have some questions in the other thread.

y = ( 3 / 4 ) x + 3


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

There is no reason to remove the post. You can just post a new post saying that you have solved it.

Re: equation of the line

Which one that I picked for the issue of the TV's? I posted my answer in the thread. I didn't use a formula, I did a process of evaluation being that 4 more were sold than the other and the total received was provided.

Re: equation of the line

Hi mom;

That is what I am getting at.

I did a process of evaluation being that 4 more were sold than the other and the total received was provided.

You left out the condition of 4 more sold! That is what was needed to narrow down the answer.
