It seems there might be some confusion in your query. If youre asking about a line parallel to the y-axis, the equation of such a line is of the form x=k, where k is a constant. This means the line is vertical and intersects the x-axis at the point (k,0). For example, the line x=3 is parallel to the y-axis and intersects the x-axis at the point (3,0).
If youre asking about a line parallel to the line y=x2, then the equation of a parallel line would be of the form y=x+b, where b is any real number different from 2. This is because parallel lines have the same slope, and the slope of the line y=x2 is 1.
