Slope Review 2

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

How do you calculate 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 x increases, y 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 x increases, y decreases, meaning the line falls from left to right.

Back

Front

What is the slope of the line that passes through the points (-2, 8) and (0, 8)?

Back

The slope is 0.

Front

What is the slope of the line that passes through the points (-12, -5) and (0, -8)?

Back

Front

What is the slope of the line that passes through the points (-4, 7) and (-6, -4)?

Back

Front

What does a slope of 0 mean in terms of the line's orientation?

Back

A slope of 0 means the line is horizontal.

Front

What does an undefined slope mean?

Back

An undefined slope occurs when a line is vertical, meaning it goes straight up and down.
