if line k is parallel to y-axis, then the slope of line k is
A. not defined
B. not existed
C. infinite
D. others?
I know parallel to x, the slope is 0.
thanks
concept check:parallel to y-axis

y=mx + c
which would mean... if something is parallel to y axis... then x=constant (since x=0 is the Y axis)
y could be anything from 0 to infinity... thus undefined!

hi syflysun!
This is example of infinite slope.

This is example of infinite slope.
Follow this link to see more details:Consider the linear function:
y = a + bx
b is the slope of the line. Slope means that a unit change in x, the independent variable will result in a change in y by the amount of b.
slope = change in y/change in x = rise/run

The terminology I have always used is an undefined slope. Given slope = change in y over change in x -- if the line is parallel to the y-axis, the change in x is zero. Anything divided by zero is undefined.
