I think you mean
y = x/2 - 4
then if x = 2
y = 1-4 = -3
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.

awesome. thank you sir!
how would you graph 12x-3y=7 and x=2+13y?
