Can you explain in your own words why the line y = –2 is a horizontal line?

Please don't just say, "Yes". Explain it.


Answer by  Slush (41)

Y is a horizontal value and X is a vertical value. When there is a y and no x, it is always a horizontal (side to side) line. When there is an x and no y, it is always a vertical (up and down) line. For example, y = -2 is a horizontal line with no x intercept.

On a linear graph, the y-axis is vertical. If you go to the point where y=-2 and draw a line, it would be horizontal and parallel to the x-axis.
