To find the equation of the line that passes through the point
and has a slope of zero, we need to understand what a slope of zero means. A slope of zero indicates a horizontal line.A horizontal line has the same y-coordinate for all points on the line. Therefore, the equation of a horizontal line is always in the form
, where
is a constant.In this case, since the line passes through the point
, the y-coordinate is 7. Therefore, the equation of the line is
.So, the correct answer is:C.
