    Gradients and the sort =[

    Heya! =]

    I need help with a fairly easy maths assignment. I can't find my textbook, so I'm not sure how the formulas went. But I think it was a really easy process. =]

    Basically, we have to find the gradients of these measurements that we took. If you guys can guide me with one of the questions, then I should be able to figure out the rest for myself. =]

    Okay, so for one measurement, I took a measurement of 13cm vertically. And a measurement of 100cm horizontally. I should be able to find the gradient from those two, right? =[

    (This is a picture of how the thing we measured looked like - Click

    I -think- it went something like, y-step over x-step. So that gives me a gradient of 0.13? Is that right? (It's not isn't it. =[ )

    Thanks if you reply! =]

    m = \frac{13 - 0}{0 - 100} = -0,13

    Awesome, thanks!

    But where does that 0 come from?

    Because if that 0 represents the horizontal gradient, why are we putting it in twice?

    I really need some more information please =]
