    to start, solve the equation for y.

    I have y=5x-4/2

    x can be dependant on y :)

    that is wrong. just do the basic algebra to get everything from the right side to the left until y is the only thing left on the right side.

    No matter what way I do it, I still end up getting the same thing

    so your original equation first becomes x-3 = -1/2y

    then you multiply both sides by -2

    so you get y=-2x+6

    I appreciate it very much. I just do not see where you multiply both sides by -2

    I am just confused.

    well you're trying to get rid of the -1/2 on the right side. to do this, you can multiply by -2. but remember that what you do to one side, you have to do to the other.

    no problem. and from that new equation, you should be able to see the slope fairly easily. if not, look through your notes/textbook.
