Slope from a Graph

Front

What is the definition of slope?

Back

Slope is a measure of the steepness of a line, calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.

Front

How do you calculate the slope from a graph?

Back

To calculate the slope from a graph, identify two points on the line, determine the rise (change in y) and run (change in x), and use the formula: Slope = rise/run.

Front

What is the slope of a line that rises 3 units and runs 4 units?

Back

Front

What is the slope of a line that falls 2 units and runs 1 unit?

Back

The slope is -2.

Front

What does a positive slope indicate about a line?

Back

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

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves 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 type of slope is it?

Back

It is a negative slope.

Front

If a line has a slope of 2, what type of slope is it?

Back

It is a positive slope.
