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 a line.

Front

How do you find the slope between two points (-4, 10) and (-6, 8)?

Back

Using the slope formula: m = (8 - 10) / (-6 + 4) = 1.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates that the line is vertical.

Front

What is the slope of a line that rises 3 units for every 4 units it runs?

Back

The slope is 3/4.

Front

What is the slope of a line that falls 4 units for every 3 units it runs?

Back

The slope is -4/3.

Front

If a line has a slope of -1/4, what does this mean?

Back

This means that for every 4 units moved to the right, the line falls 1 unit.

Front

What is the rate of change in a linear relationship?

Back

The rate of change is the same as the slope of the line.

Front

How do you determine the slope from a graph?

Back

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

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.
