Front

What is the slope of a vertical line?

Back

Undefined

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

What does a positive slope indicate about a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

The line falls from left to right.

Front

What is the slope of the line that passes through the points (−9, -6) and (−9, -10)?

Back

Undefined

Front

If the slope of a line is 0, what does that tell you about the line?

Back

The line is horizontal.

Front

If the slope of a line is undefined, what does that tell you about the line?

Back

The line is vertical.
