    The first thing I would probably do is distribute (multiply) the - 5/2 into the parenthesis:

    = (-5/2) x + (-20/2)

    Notice how I am not putting the x into the fraction. This is to make it easier to see the slope-intercept form.

    Lets simplify the (-20/2) and then add 7 to both sides:

    y - 7 = (-5/2) x - 10

    y = (-5/2) x - 3

    Your answer would then be:

    y = (-5/2) x - 3

    y = mx + b

    Since it is now in the requested format.
