What is the slope m of a line that is perpendicular to the line represented by x = 6? (If an answer is undefined, enter UNDEFINED.)

No, as I said the given line has undefined slope, so a perpendicular

line would have a slope of 0.

it is undefined??

To find the slope of a line perpendicular to another line, we can use the fact that perpendicular lines have slopes that are negative reciprocals of each other.

The equation x = 6 represents a vertical line passing through the x-coordinate 6. Since vertical lines have an undefined slope, the slope of a line perpendicular to x = 6 is UNDEFINED.

In general, for a line in the form x = a, where "a" is a constant, the slope is undefined because the line is vertical.

A line of the form x = c, where c is a constant is a vertical line and has an undefined slope

A line of the form y = k, where k is a constant has a slope of 0.

Lines that are perpendicular have slopes that are negative reciprocals of each other.

So .....
