    Smile y=mx+b

    I am working with y=mx +b

    I have y= x/-3 +1/3

    So I would go up to 1/3 then mark a dot, for the next dot how do I do x/-3?

    What would the slope be?

    Thanks , this is really confusing and if I have other quick easy questions like these on y=mx+b could I post them in here?

    So then does the negative always go to the top number in a fraction? The bottom number is positive? If both the top and bottom were negative then both would turn into positive?

    The negative was at the 3 and it jumped up to the 1, I thought it would be up 1 and to the left 3, thanks.

    ... up 1 and 3 left is the same as down 1 and 3 right.

    Thanks and if the slope is just plain x then it is considered 1,1 right?
