positive negative slope

Front

What is the definition of a positive slope?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, resulting in an upward trend on a graph.

What is the definition of a negative slope?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, resulting in a downward trend on a graph.

Front

What does a zero slope represent?

Back

A zero slope represents a horizontal line where the y-value remains constant as the x-value changes.

Front

How can you visually identify a positive slope on a graph?

Back

A positive slope can be identified by a line that rises from left to right.

Front

How can you visually identify a negative slope on a graph?

Back

A negative slope can be identified by a line that falls from left to right.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined because the change in x is zero, leading to division by zero.

Front

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Back

The formula for calculating the slope (m) is m = (y2 - y1) / (x2 - x1).

Front

If a line has a slope of 3, what does this indicate about the relationship between x and y?

Back

A slope of 3 indicates that for every 1 unit increase in x, y increases by 3 units.

Front

What is the slope of a line that is perfectly horizontal?

Back

The slope of a perfectly horizontal line is 0.

Front

What is the slope of a line that is perfectly vertical?

Back

The slope of a perfectly vertical line is undefined.
