Finding Slope

Front

What is the formula to find the slope of a line between two points (x1, y1) and (x2, y2)?

Back

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

Front

If a line has a slope of 3, what does this mean in terms of rise over run?

Back

For every 3 units up (rise), the line goes 1 unit to the right (run).
