    Question confusing graphs

    first, about me. i am using oddeseyware for school, a division of switched on schoolhouse. this means that i am doing problems on a computer, and the computer grades them. sometimes its a bit finicky about the answers it will take, but i've learned to accomodate it.

    so i have this problem. i am asked to find the slope and y intercept of a linear equation in standard form. easy enough right? so i get to work.

    5x + 6y = 24
    i decide to just change it to y = mx+b because thats easiest.
    6y = 5x + 24
    y = 5/6x + 4
    i assume that 5/6 is the slope and 4 is the y-intecept, but i am told that this answer is wrong. why?


    i seem to have several other problems like this. is it just my math? or something else?

    EDIT: oh geez, i just found my error. in step two 5x should have been negative... well, thanx for having the patience to read a completely pointless thread.

    5x+6y = 24

    6y = -5x+24

    y = (-5/6)x+4

    slope: -5/6
    y-intercept: 4
