Slope Basics Flashcard

Front

What is the definition of slope?

Back

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

Front

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

Back

Slope (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 the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

If a line has a slope of -2, what does this mean?

Back

This means that for every 1 unit increase in the x-direction, the y-value decreases by 2 units.

Front

What is the slope of the line represented by the equation y = 1/2x + 3?

Back

The slope of the line is 1/2.

Front

What type of slope does the line y = -4?

Back

The line y = -4 has a slope of 0 (horizontal line).

Front

What type of slope does the line x = 2 represent?

Back

The line x = 2 has an undefined slope (vertical line).
