Slope Practice

Front

What is the slope of a vertical line?

Back

Undefined

Front

What is the slope of a horizontal line?

Back

Zero

Front

Define slope in mathematical terms.

Back

Slope is defined as the ratio of the rise (change in y) to 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 x increases, y also increases.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the slope of the line represented by the equation y = 3x + 2?

Back

The slope is 3.

Front

If a line has a slope of -2, what does this mean in terms of rise and run?

Back

For every 2 units the line falls (rise), it moves 1 unit to the right (run).

Front

What is the slope of the line that passes through the points (1, 2) and (4, 5)?

Back

The slope is (5 - 2) / (4 - 1) = 1.

Front

What is the significance of a slope of 0 in a real-world context?

Back

A slope of 0 indicates no change; for example, a flat road.
