I am getting stuck on graphing equations.

when something says y=1/2x-4.....I am supposed to put in numbers for x. however, I am stuck on the concept of how to divide by the fraction. Lets say x=2

y=1/2(2)-4

I am totally stumped on if I need to make two into a fration or mulitply two by the denominator.
