Finding Slope from a Table, Graph, and Points

Front

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

Back

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

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

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

Back

For every 3 units of rise, there is a run of 1 unit.
