Reminder: the x-axis really runs left and right, and the y-axis runs up and down.

What is the y-axis line?

The vertical line is known as the y axis. It is nothing more than a measuring stick to count how far “up or down” a point is from the horizontal line. The horizontal line, then, is known as the x axis and measures the distance left or right from the vertical line.

Which axis is vertical?

A y-axis is the vertical axis on the Cartesian coordinate plane. The y-axis starts at negative infinity and increases to positive infinity.

Is y-axis up or down?

A coordinate grid has two perpendicular lines, or axes (pronounced AX-eez), labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis.

Is Y horizontal or vertical?

A vertical line is a line extending up and down. On a table (like the one shown to the right), the legs of the table are vertical lines. The y-axis is an example of a vertical line.

Is vertical up and down?

A vertical line is one the goes straight up and down. The horizontal line is a straight line that goes from left to right. Parallel lines are lines which are always the same distance apart and never meet.

Does the y-axis go first?

In an ordered pair, such as (x, y), the first value is called the x-coordinate and the second value is the y-coordinate. Note that the x-coordinate is listed before the y-coordinate. Since the origin has an x-coordinate of 0 and a y-coordinate of 0, its ordered pair is written (0, 0).

Which is the y-axis on a bar graph?

In most bar graphs, like the one above, the y-axis runs vertically (us and down). Sometimes bar graphs are made so that the bars are sideways like in the graph to the left. Then the y-axis is horizontal (flat). Typically, the y-axis has numbers for the amount of stuff being measured.
