Front

What is the equation of a horizontal line?

Back

Front

If a line has a slope of 0, what does that indicate?

Back

A slope of 0 indicates that the line is horizontal.

Front

If a line has an undefined slope, what does that indicate?

Back

An undefined slope indicates that the line is vertical.
