Slope

Front

What is the definition of slope?

Back

Slope is a measure of the steepness or incline of a line, typically represented as the ratio of the vertical change to the horizontal change between two points on the line.

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 line that rises from left to right?

Back

Positive slope.

Front

What is the slope of a line that falls from left to right?

Back

Negative slope.

Front

What is the slope of a horizontal line?

Back

0.

Front

What is the slope of a vertical line?

Back

Undefined.

Front

If a line has a slope of 2, what does this mean?

Back

For every 2 units the line rises, it moves 1 unit to the right.

Front

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

Back

2.

Front

What does it mean if the slope is undefined?

Back

The line is vertical and does not have a defined slope.

Front

If a line has a slope of 0, what can be said about its direction?

Back

The line is horizontal.
