Positive or Negative Slope from a Graph

Front

What is a positive slope?

Back

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

Front

What is a negative slope?

Back

A negative slope indicates that as the x-values increase, the y-values decrease, resulting in a downward trend on a graph.

Front

How can you 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 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 does a slope of zero indicate?

Back

A slope of zero indicates a horizontal line, meaning there is no change in y-values as x-values change.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line, meaning x-values do not change as y-values change.

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 mean?

Back

A slope of 3 means that for every 1 unit increase in x, the y-value increases by 3 units.

Front

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

Back

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

Front

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

Back

The slope of a perfectly horizontal line is 0.
