    1/2

    Step-by-step explanation:

    The first thing you want to do is get y by itself. Subtract 7 from both sides:

    2x-4y=-7

    and then subtract 2x (the goal is to make your equation look like this: y=mx+b):

    -4y = - 2x-7

    Now, y is mostly isolated, all you have to do now is divide both sides by - 4 in order for y to be completely by itself:

    y=-2/-4x - 7/-4

    Simplify completely:

    y=1/2x+7/4

    Now you have your equation you can easily read it as y=mx+b.

    * * m is slope & b is the y-intercept**

    So your slope would be: 1/2
