Provide an appropriate response.Explain in your own words why equations of the form y = b have graphs that are horizontal lines.
What will be an ideal response?
The second coordinate of any point on the graph is b, regardless of the first coordinate, so the graph is a line parallel to the x-axis and ?b? units above or below it. Thus, the graph is a horizontal line.
