Question

Select the correct answer from each drop-down menu.

A line parallel to the (x-axis or y-axis) has no defined slope, and a line parallel to the (x-axis or y-axis) has a slope of zero.

Answer 1

y-axis, x-axis

Explanation:

Answer 2

The answer to your question is x-axis, y-axis

Explanation:

To answer this question just remember the equation of the slope

m =
`(y2 - y1)/(x2 - x1)`

Then:

If the numerator is zero, the line is parallel to the x-axis and the slope will be zero.

If the denominator is zero, the line is parallel to the y-axis and the slope will be undefined.
