Front

What is the definition of slope?

Back

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

How is slope calculated?

Back

Slope (m) is calculated using the formula: m = \frac{\text{rise}}{\text{run}}.

What does a positive slope indicate?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, resulting in an upward trend.

What does a negative slope indicate?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, resulting in a downward trend.

If a line goes through the points (2, 3) and (4, 7), what is the slope?

Back

The slope is 2, calculated as m = \frac{7-3}{4-2} = \frac{4}{2} = 2.

If a line has a slope of -1, what does this tell you about its steepness?

Back

A slope of -1 indicates that the line descends at a 45-degree angle.
