Answer: 1st Graph.
The first graph represents the problem because 1/2x is the x intercept, so 1/2 intersects the x-axis.
Basically, the x intercepts are [tex](\frac{\sqrt{2} }{2},0)(-\frac{\sqrt{2} }{2},0)[/tex]
They're aren't any Y intercepts because it will never intersect the y-axis, so it must be parallel.
Hence, the 1st Graph represents your equation.
