Calculate the slope of the line that passes through the points (3, 4) and (3, 8).

Back

Undefined (vertical line)

Front

If a line has a slope of -2, what does this indicate about the direction of the line?

Back

The line falls as it moves from left to right.

Front

What is the formula to calculate the slope (m) between two points (x1, y1) and (x2, y2)?

Back

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

Front

If the slope of a line is 0, what can be said about the line?

Back

The line is horizontal.
