I have to find the y-intercept in a problem that looks like this: 3x+3y=12. Also in one like this 4y-2x-3=0. How do I do that? Please show me someone.

I need to understand how to find the difference from two points mathematically. I have this equation, but I'm not sure how to use it. It looks like this: (x2-x1)^2 + (y2-y1)^2. Can some one help me with an example. On the reveiw it has one of these for (-2,3) (6,7). I have another question and you can go for that one too. Its in this section.

(4/5)^2+sin^2=1
16/25+sin^2=1
sin^2=9/25
sin=3/5, or pi/300

i know that's not right though because of the range, and also it just doesn't sound right...

As this is an english speaking, site perhaps there may be bias but let me wait for the best answer.
