The equation is
Explanation:
We know that slope is rise over run, and that all lines parallel to the x axis are horizontal. A perfectly horizontal line has a slope of zero because it never rises. We know that the equation is y=7 because it passes through point (3,7), and 7 is the y-coordinate of that point (remember we don't really care about the 3 because since the line is parallel to the x-axis, it will pass through all values of x, so the 3 is irrevalent).
