The x-axis is a horizontal line with equation y = 0. The y-axis is 90 degrees and thus it is perpendicular to the x-axis and the y-axis is a vertical line with the equation x = 0. The equation x = 0 contains the point (0, 0), so x = 0 be the answer
Also, each line that passes through the orign (0, 0), there's only one answer, x = 0.

Look at a cartesian plane. The x-axis is a horizontal line with equation y=0. The y-axis is 90 degrees, thus perpendicular, to the x-axis. And the y-axis has the equation x=0. The equation x=0 contains the point (0,0), so x=0 would be the answer. And, as for writing an equation for EACH line that passes through the origin (0,0), don't worry--there's only one answer, x=0.
It's a little confusing to explain in words. Hope you understand!

By Euclid's 4th postulate, there is a unique line that passes through a point and is perpendicular to a given line. Since the y-axis, indeed, satisfies these criterion, it is the only line as such.
