What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

What does a slope of undefined indicate about a line?

Back

An undefined slope indicates that the line is vertical.

If the slope of a line is positive, what does that tell you about the line's direction?

Back

A positive slope means the line rises from left to right.

Front

If the slope of a line is negative, what does that tell you about the line's direction?

Back

A negative slope means the line falls from left to right.
