Front

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

Back

m = \frac{y2 - y1}{x2 - x1}

Front

What is the slope of the line that passes through the points (7, 3) and (13, 8)?

Back

m = \frac{5}{6}

Front

What does a slope of 0 indicate about a line?

Back

The line is horizontal.

Front

What does a negative slope indicate about a line?

Back

The line decreases as it moves from left to right.
