The graphs of y = 0 and y = –4 are different.
The graph of y = 0 is a horizontal line that passes through the y-axis at y = 0. It represents all the points on the coordinate plane where the y-coordinate is equal to 0.
On the other hand, the graph of y = –4 is also a horizontal line, but it is positioned 4 units below the x-axis. It represents all the points on the coordinate plane where the y-coordinate is equal to –4.
Visually, the graph of y = 0 is a straight line at the x-axis, while the graph of y = –4 is a straight line parallel to the x-axis, but situated below it.
How do the graphs of y = and y = – 4 compare?
