Front

What is the slope of a line that decreases by 2 units for every increase of 1 unit in x?

Back

The slope is -2.

Front

What is the definition of slope in a linear equation?

Back

Front

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

Back

Front

What does it mean if a line has a positive slope?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward trend.

Front

What does it mean if a line has a negative slope?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward trend.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, y).
