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 (5, -6) and (12, -20)?

Back

m = (-20 - (-6)) / (12 - 5) = -14 / 7 = -2.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

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

Back

m = (8 - 10) / (-6 - (-4)) = -2 / -2 = 1.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

How do you find the slope of a line in simplest form from a graph?

Back

Identify two points on the line, calculate the rise over run (change in y over change in x).

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

How do you calculate the slope of a line given the points (2, 3) and (6, 7)?

Back

m = (7 - 3) / (6 - 2) = 4 / 4 = 1.

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

What is the slope of a line that has a rise of -1 and a run of 4?

Back

The slope is -1/4.
