Slope (graphs, tables, points)

Front

What is the definition of slope?

Back

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

What does a positive slope indicate?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, showing a direct relationship.

What does a negative slope indicate?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, showing an inverse relationship.

Front

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

Back

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

If a line has a slope of 4, what does this mean in terms of rise and run?

Back

For every 4 units of rise, there is a 1 unit run.

What is the slope of the line represented by the points (2, 3) and (4, 7)?

Back

Slope = (7 - 3) / (4 - 2) = 4 / 2 = 2.

What is the rate of change in a linear relationship?

Back

The rate of change is the same as the slope, indicating how much y changes for a change in x.
