Slope: Rise over Run

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is zero.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves from left to right.

Front

How is slope calculated?

Back

Slope is calculated as the change in y (rise) divided by the change in x (run), or slope = rise/run.

Front

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

Back

The slope of the line is 2.

Front

What is the slope of the line represented by the equation y = -rac{1}{2}x + 4?

Back

The slope of the line is -rac{1}{2}.

Front

If a line has a slope of 3, what does this mean in terms of rise and run?

Back

For every 3 units the line rises, it runs 1 unit to the right.

Front

What is the slope of the line that passes through the points (1, 2) and (3, 6)?

Back

The slope is 2.

Front

What is the slope of the line that passes through the points (2, 3) and (2, 5)?

Back
