Front

What is the slope of the line if it rises 5 units and runs 3 units?

Back

5/3

Front

What is the slope of the line if it falls 5 units and runs 3 units?

Back

-5/3

Front

How do you calculate slope using a graph?

Back

Slope is calculated as rise over run.

Front

In the equation y=mx+b, what does the 'm' represent?

Back

The 'm' represents the slope.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls from left to right.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

If a line has a slope of -1, what does this mean?

Back

For every 1 unit the line falls, it runs 1 unit to the right.

Front

What is the formula for slope?

Back

Slope (m) = (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are two points on the line.
