Module 5 Flashcardizz - Questions

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, usually represented as 'm'. It is calculated as the ratio of the rise (change in y) over the run (change in x).

Front

Find the slope of the line given by the points (2, 3) and (4, 7).

Back

The slope is calculated as m = (y2 - y1) / (x2 - x1) = (7 - 3) / (4 - 2) = 4/2 = 2.

Front

What does a positive slope indicate?

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?

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 the slope of a horizontal line?

Back

The slope of a horizontal line is 0, indicating 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 run (change in x) is 0, leading to division by zero.

Front

Define discrete data.

Back

Discrete data consists of distinct or separate values, often counted in whole numbers, such as the number of students in a class.

Front

Define continuous data.

Back

Continuous data can take any value within a given range and is often measured, such as height or weight.

Front

What is the slope of the line represented by the equation y = 4/3x + 2?

Back

The slope of the line is 4/3.

Front

What is the slope of the line represented by the equation y = -2x + 5?

Back

The slope of the line is -2.
