Slope - Rise over Run

Front

What is the definition of slope?

Back

Slope is a measure of the steepness of a line, calculated as the ratio of the vertical change (rise) to the horizontal change (run).

Front

What does 'rise over run' mean in the context of slope?

Back

'Rise over run' refers to the formula for calculating slope, where 'rise' is the change in the y-coordinate and 'run' is the change in the x-coordinate.

Front

How do you calculate the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

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

If a line rises 3 units and runs 4 units, what is the slope?

Back

The slope is 3/4.

Front

If a line falls 2 units and runs 5 units, what is the slope?

Back

The slope is -2/5.

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

If a slope is -1, what does this mean in terms of movement?

Back

For every 1 unit the line moves down, it moves 1 unit to the right.
