#### Question

X-axis and line x = - 4 are parallel lines. What is the distance between them?

#### Solution

**Disclaimer:** The question is incorrect. The question should be "Y-axis and line x = - 4 are parallel lines. What is the distance between them? **or** X-axis and line y = - 4 are parallel lines. What is the distance between them?"

If the question is "Y-axis and line x = - 4 are parallel lines. What is the distance between them?" then the answer is as follows.

x = −4 is the equation of the line parallel to the Y-axis at a distance of 4 units and to the left of Y-axis.

Thus, the distance between them is 4 units.

**OR**

If the question is "X-axis and line y = - 4 are parallel lines. What is the distance between them?" then the answer is as follows.

y = −4 is the equation of the line parallel to the X-axis at a distance of 4 units and below the X-axis.

Thus, the distance between them is 4 units.
