SLOPE - practice test Dec 2025

Front

What is the slope of a graph?

Back

The slope of a graph represents the rate of change of a line, calculated as the rise (change in y) over the run (change in x).

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, showing an upward trend.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, showing a downward trend.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What is a proportional relationship in a graph?

Back

A proportional relationship is when two quantities maintain a constant ratio, represented by a straight line through the origin.

Front

How can you identify a proportional relationship on a graph?

Back

A proportional relationship can be identified by a straight line that passes through the origin (0,0).

Front

What does it mean if a graph has a slope of 0?

Back

A slope of 0 means the line is horizontal, indicating no change in y as x changes.

Front

What does it mean if a graph has an undefined slope?

Back

An undefined slope means the line is vertical, indicating that x does not change as y changes.
