Since you know the slope of line \(y_{1}\) is 2 and that the lines are parallel, you can find the slope of \(y_{2}\) by flipping the slope upside down and making it negative (-\(\frac{1}{2}\). You can see on the coordinate grid that \(y_{2}\) crosses the y-axis at 1. When you piece these facts together into slope-intercept form, it becomes \(y_{2}\) = -\(\frac{1}{2}\)x + 1.
