Identifying Slope From a Graph

Front

What is the formula for calculating slope (m)?

Back

m = \frac{rise}{run}

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

What two characteristics does the slope of a line represent?

Back

Steepness and Direction.

Front

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

Back

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

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is zero.

Front

What does a positive slope indicate about the direction of a line?

Back

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

Front

What does a negative slope indicate about the direction of a line?

Back

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

Front

If a line has a slope of 3/7, what does this mean in terms of rise and run?

Back

For every 3 units of rise, there are 7 units of run.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

How can you determine if a slope is positive, negative, or zero from a graph?

Back

A positive slope rises, a negative slope falls, and a zero slope is horizontal.
