Well... mammals are animals, so I say we are animals.

The bible did make the point that we are not animals... however.

Science may say we are in the 'animal' group, but really, if you think about it, we are so different from everything else, we can reason, we are advanced, and we have rights...

Welcome littlelittle, hope you enjoy your time here

If you need help with a problem, please post in the Help Me section

I hope this is the right format:

We can take away the brackets immediately:

Then, using Bodmas (Brackets, Order, Division Multiplication, Addition Subtraction), or Pemdas (Parentheses, Exponents, Multiplication Division, Addition Subtraction), to work through the problem. Remember to do multiplication and division first. Also remember that:

and

So let's clear up the multiplications and divisions first

Please ask if you have further questions.

When do you think we'll ever find out for certain which gender is smarter? Perhaps we are supposed to never find out. All that has been said so far has been based on observations, experiments, and surveys. What we really need is a stringent mathematical proof.

Listening to Machinae Supremacy Theme from Jets-n-guns at the moment, it's pretty good. No lyrics.

Lol, interesting answer espeon... it does, in a way, make sense... generally.

Sorry littlelittle, you're right, I don't know how I messed up the answers for that one, I've changed the answers so they're right now.

Well, let's take for example, the coordinates (1,4) (-3, 5).
The coordinates are of the form (x1, y1) (x2, y2), so we can substitute them into the formula:
(y - y1)(x2 - x1) = (x - x1) (y2 - y1)
    (y - 4)(-3 - 1) = (x - 1)(5 - 4)
         (y - 4)(-4) = (x - 1)(1)
Using the distributive law:
            -4(y - 4) = 1(x-1)
           -4y + 16 = x - 1
                   -4y = x - 17
∴                   y = -1/4x + 17/4

(I personally don't use this method [although it would probably benefit me if I did], instead, I find the gradient (y2-y1)/(x2-x1), then substitute the coordinate points in to solve for c)
