Front

If a line rises 2 units for every 1 unit it runs, what is the slope?

Back

The slope is 2.

Front

What does a slope of zero indicate about a line?

Back

A slope of zero indicates that the line is horizontal.

Front

What does a positive slope indicate about the relationship between two variables?

Back

A positive slope indicates that as one variable increases, the other variable also increases.

Front

What does a negative slope indicate about the relationship between two variables?

Back

A negative slope indicates that as one variable increases, the other variable decreases.

Front

How can you determine the slope from a graph?

Back

The slope can be determined by selecting two points on the line and using the formula (change in y) / (change in x).

Front

What is the formula for calculating slope?

Back

The formula for calculating slope is m = (y2 - y1) / (x2 - x1).
