Module 5 Flashcardizz - Questions

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 ratio of the rise (change in y) over the run (change in x).

Front

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

Back

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

Front

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.

Front

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.

Front

What is a discrete variable?

Back

A discrete variable is a type of quantitative variable that can take on a countable number of values, such as the number of students in a class.

Front

What is a continuous variable?

Back

A continuous variable is a type of quantitative variable that can take on an infinite number of values within a given range, such as time or temperature.

Front

Give an example of a discrete variable.

Back

The number of orange Skittles in a bag is a discrete variable because it can only take whole number values.

Front

Give an example of a continuous variable.

Back

The time it takes for a car battery to die is a continuous variable because it can take any value within a range.

Front

What is the significance of the slope in real-world applications?

Back

The slope can represent rates of change, such as speed in a distance-time graph or cost per item in a price-quantity graph.

Front

What does it mean if a line has a slope of zero?

Back

A slope of zero indicates a horizontal line, meaning there is no change in y as x changes.
