Question

10/20
the y - axis is:
a positive line
a vertical line
a negative line
a horizontal line

Explanation:

In a Cartesian coordinate system, the Y - axis is defined as the vertical line that runs up and down, while the X - axis is the horizontal line that runs left and right. A "positive line" or "negative line" is not an accurate description of the Y - axis as it has both positive and negative values (above and below the origin), and it is not horizontal. So the Y - axis is a vertical line.

Answer:

B. A vertical line
