I am getting stuck on graphing equations.
when something says y=1/2x4.....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.

I think you mean
y = x/2  4
then if x = 2
y = 14 = 3

how would you graph 12x3y=7 and x=2+13y?
