Slope - The Basics

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y (vertical change) divided by the change in x (horizontal change).

Front

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

Back

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

Front

What is the slope of the line passing through the points (10, 4) and (12, 9)?

Back

5/2

Front

Is slope a fraction?

Back

True, slope can be expressed as a fraction.

Front

Can slope be defined as the change in y divided by the change in x?

Back

True.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves from left to right.

Front

What is the slope of the line passing through the points (2, 7) and (5, 3)?

Back

-4/3

Front

If a line has a slope of 0, what does that mean?

Back

A slope of 0 means the line is horizontal.

Front

If a line has an undefined slope, what does that mean?

Back

An undefined slope means the line is vertical.
