Question #af8ff

Answer 1

False it is a vertical line.

Explanation:

The line with equation x = c, where c is a constant is a vertical line, parallel to the y-axis and passing through all points in the plane with an x-coordinate of c.

In this case c = 11 and x = 11 is a vertical line.

Horizontal lines have equation y = c, where c is a constant and are parallel to the x-axis passing through all points in the plane with a y-coordinate of c.

Here is the graph of x = 11
