24-25 Math I Slope from a Graph

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise (change in y) over the run (change in x).

Front

How do you find the slope from a graph?

Back

To find the slope from a graph, select two points on the line, determine the rise and run between them, and divide the rise by the run.

Front

What does a slope of 4/5 indicate?

Back

A slope of 4/5 indicates that for every 5 units moved horizontally to the right, the line rises 4 units.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined because the run (change in x) is zero.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0 because there is no rise (change in y).

Front

If a line rises as it moves from left to right, what can be said about its slope?

Back

If a line rises from left to right, its slope is positive.

Front

If a line falls as it moves from left to right, what can be said about its slope?

Back

If a line falls from left to right, its slope is negative.

Front

What is the slope of a line that is perfectly vertical?

Back

The slope of a perfectly vertical line is undefined.

Front

What is the slope of a line that is perfectly horizontal?

Back

The slope of a perfectly horizontal line is 0.

Front

How do you determine if a slope is positive, negative, or undefined?

Back

A slope is positive if the line rises, negative if it falls, and undefined if the line is vertical.
