Identifying Slope From a Graph

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, typically represented as 'm'. It is calculated as the change in y (vertical) divided by the change in x (horizontal).

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 (change in y) and run (change in x), and then use the formula: slope (m) = rise/run.

What does a positive slope indicate?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, showing an upward trend.

What does a negative slope indicate?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, showing a downward trend.

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0, meaning there is no vertical change as the x-value changes.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined because the change in x is 0, leading to division by zero.

What does a slope of 1/2 mean?

Back

A slope of 1/2 means that for every 2 units you move horizontally to the right, you move 1 unit up.

What does a slope of -3/4 mean?

Back

A slope of -3/4 means that for every 4 units you move horizontally to the right, you move 3 units down.
