Positive or Negative Slope from a Graph

Front

What is a positive slope?

Back

A positive slope indicates that as the x-value increases, the y-value also increases. The line rises from left to right.

Front

What is a negative slope?

Back

A negative slope indicates that as the x-value increases, the y-value decreases. The line falls from left to right.

Front

How can you identify a positive slope on a graph?

Back

A positive slope is identified by a line that moves upward as it goes from left to right.

Front

How can you identify a negative slope on a graph?

Back

A negative slope is identified by a line that moves downward as it goes from left to right.

Front

What does a slope of zero mean?

Back

A slope of zero means that the line is horizontal, indicating no change in y as x changes.

Front

What does an undefined slope mean?

Back

An undefined slope occurs with a vertical line, where x remains constant while y changes.

Front

What is the formula for calculating slope?

Back

The formula for slope (m) is m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Front

If a line has a slope of 3, what does this indicate?

Back

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

Front

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

Back

A slope of -2 indicates that for every 1 unit increase in x, y decreases by 2 units.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.
