Question

which number line represents the x - axis when it is extended? -5 -4 -3 -2 -1 0 1 2 3 4 5 which number line represents the y - axis when it is extended? 1 0 5 4 3 2 1 1 0 -1 -2 -3 -4 -5 1 0 -5 -4 -3 -2 -1 1 0 1 2 3 4 5

Explanation:

Step1: Recall x - axis property

The x - axis is a horizontal number line with 0 at the center, negative numbers to the left and positive numbers to the right. The given horizontal number line from - 5 to 5 when extended represents the x - axis.

Step2: Recall y - axis property

The y - axis is a vertical number line with 0 at the center, negative numbers below and positive numbers above. Among the vertical number lines, the one with 0 in the middle, negative numbers decreasing downwards and positive numbers increasing upwards represents the y - axis.

Answer:

The horizontal number line from - 5 to 5 represents the x - axis when extended. For the y - axis, the vertical number line with 0 in the middle, negative numbers below (decreasing as we go down) and positive numbers above (increasing as we go up) represents the y - axis.
