Would these be parallel:

y = 1/2x + 4

x = 1/2

2x + y = 1

y = 1/2x +1

 

I do know that Y = 1/2x + 1 and y = 1/2x + 4 are parallel but i'm confused on the others

I've found the images aren't always visible also!  It's usually a temporary glitch.

 

However, for lines to be parallel, the gradients must be the same.  If you express the line in the form y = m*x + c where m and c are constants then m must be the same for parallel lines.

The line x = 1/2 is just a vertical line at x = 1/2 (with an infinite slope!)

This graph should help with the answer.
