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 (rise) to the horizontal change (run) between two points on the line.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula: 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

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, meaning the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, meaning the line falls from left to right.

Front

If the slope of a line is 4/3, what does this mean in terms of rise and run?

Back

For every 4 units of vertical rise, there is a corresponding horizontal run of 3 units.

Front

Given the points (3, 18) and (0, 18), what is the slope?

Back

The slope is 0.

Front

Given the points (-2, -9) and (-1, -3), what is the slope?

Back

The slope is -6.

Front

What are the four types of slope?

Back

1. Positive slope 2. Negative slope 3. Zero slope 4. Undefined slope.
