Math 8: Lesson 3.3-3.4 Review

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, typically represented as 'm' in the slope formula.

Front

What is the slope formula?

Back

The slope formula is m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Front

What does an increasing slope indicate?

Back

An increasing slope indicates that as the x-value increases, the y-value also increases.

Front

What does a decreasing slope indicate?

Back

A decreasing slope indicates that as the x-value increases, the y-value decreases.

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

If a line has a slope of 1, what does that mean?

Back

A slope of 1 means that for every unit increase in x, y increases by the same amount.

Front

If a line has a slope of -1, what does that mean?

Back

A slope of -1 means that for every unit increase in x, y decreases by the same amount.

Front

What is the meaning of a slope of 0/1?

Back

A slope of 0/1 indicates a horizontal line, where there is no change in y as x changes.

Front

What does it mean if a line is described as 'increasing'?

Back

It means that the line rises from left to right.
