Slope Review

Front

What is the definition of slope?

Back

Slope is the ratio of the rise (vertical change) to the run (horizontal change) between two points on a line.

Front

What is the formula to calculate slope?

Back

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

Front

What does the 'm' represent in the equation y=mx+b?

Back

The 'm' represents the slope of the line.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

The line is horizontal and has no slope.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Use the formula: m = (y2 - y1) / (x2 - x1).

Front

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

Back

The slope is 2.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What is the slope of a line parallel to the x-axis?

Back

The slope of a line parallel to the x-axis is 0.
