Analyzing Linear Relationships Skills Review

Front

What is 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.

Front

What is 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 means that the line is horizontal, indicating that there is no change in the y-value as the x-value changes.

Front

What does an undefined slope indicate?

Back

An undefined slope occurs in a vertical line where the x-value does not change, leading to a division by zero in the slope formula.

How do you write the equation of a line given a slope and y-intercept?

Front

How do you interpret the slope of a line in a real-world context?

Back

The slope represents the rate of change; for example, in a speed graph, it indicates how fast something is moving.

Front

What is the relationship between slope and steepness?

Back

A steeper slope has a larger absolute value, indicating a greater rate of change, while a flatter slope has a smaller absolute value.
