Question

multiple-choice question
the y axis is drawn
horizontally and on the left edge of the x axis
horizontally and on the right edge of the x axis
vertically and on the right edge of the x axis
vertically and on the left edge of the x axis

Explanation:

In a Cartesian coordinate system, the y - axis is a vertical line. The x - axis is horizontal, and the y - axis intersects the x - axis at the origin. The y - axis is drawn vertically, and it is on the left edge of the x - axis (when the x - axis is drawn horizontally with positive direction to the right). So we analyze each option:

• Option 1: The y - axis is not horizontal, so this is wrong.
• Option 2: The y - axis is not horizontal, so this is wrong.
• Option 3: The y - axis is vertical but not on the right edge of the x - axis (usually, the positive y - axis is on the left side of the positive x - axis direction), so this is wrong.
• Option 4: The y - axis is vertical and on the left edge of the x - axis, which matches the definition of the Cartesian coordinate system.

Answer:

D. vertically and on the left edge of the x axis
