Slope All Ways

Front

What is the definition of slope in mathematics?

Back

Slope is a measure of the steepness or incline of a line, typically represented as the ratio of the vertical change to the horizontal change between two points on the line.

How is slope calculated using two points (x1, y1) and (x2, y2)?

Back

Slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, meaning the line rises from left to right.

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, meaning the line falls from left to right.

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0, as there is no vertical change regardless of the horizontal change.

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined, as the horizontal change is 0, leading to division by zero.

What is the formula for finding the slope from a table of values?

Back

To find the slope from a table, select two points (x1, y1) and (x2, y2) and use the formula: m = (y2 - y1) / (x2 - x1).

What is the rate of change in the context of slope?

Back

The rate of change refers to how much one quantity changes in relation to another quantity, which is represented by the slope of a line.

What does 'all of the above' imply in multiple-choice questions about finding the rate of change?

Back

'All of the above' implies that all listed methods or options are valid ways to determine the rate of change.

How can slope be interpreted in real-world scenarios?

Back

In real-world scenarios, slope can represent rates such as speed, growth, or decline, indicating how one variable changes in relation to another.
