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 relation to slope?

Back

'Rise over run' refers to the formula used to calculate 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 between 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 as it moves from left to right, what is the slope?

Back

The slope is positive.

Front

If a line falls as it moves from left to right, what is the slope?

Back

The slope is negative.

Front

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

Back

The slope is 2.

Front

What does a slope of 1/2 indicate about the line?

Back

It indicates that for every 2 units moved horizontally (run), the line rises 1 unit (rise).

Front

How can you determine if a slope is positive, negative, zero, or undefined from a graph?

Back

A positive slope rises from left to right, a negative slope falls from left to right, a zero slope is horizontal, and an undefined slope is vertical.
