Question

which statement is true?
A. A line parallel to the x axis has neither slope nor y intercept defined.
B. a line parallel to the Y axis has neither slope nor y intercept defined.
C. a line parallel to the x axis has slope defined but not y intercept.
D. a line parallel to the Y axis has a slope defined but not y intercept.

I still don't understand.

Answer 1

B is true That is because, the slope of a vertical line would be

\[\frac{y_2-y_1}{0}\] which is undefined

and a vertical line never crosses the y axis

Answer 2

A vertical line never crosses the y axis. Oh okay. Thank you!!

Answer 3

Anytime!
