Finding Slope

Front

What is the formula for finding the slope of a line?

Back

Slope (m) = (change in y) / (change in x) or rise/run.

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

Back

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

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.

Front

What is the slope of the line represented by the equation y = 3x + 2?

Back

The slope is 3.

Front

What is the slope of the line represented by the equation y = -2x + 5?

Back

The slope is -2.

Front

How do you determine the slope from a graph?

Back

Count the rise (vertical change) and run (horizontal change) between two points on the line.

Front

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

Back

The slope is 2.
