Solution

## The correct option is D 0Given: (−6,−4),(0,−4),(1,−4),(4,−4) and (8,−4) Since the y coordinate is constant (-4) for all the given points and only the x coordinate changes, the line is parallel to the x axis. As we know, Slope of x-axis is zero. Hence, The slope of line parallel to the x axis is also zero. Plot all the given points on the cartesian plane and join the points.
