Slope (Rise Over Run)

Front

What is the formula for calculating slope?

Back

Slope (m) = Rise / Run

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 a line that rises 3 units and runs 2 units?

Back

3/2

Front

What is the slope of a line that falls 5 units and runs 4 units?

Back

-5/4

Front

What type of slope does a horizontal line have?

Back

Zero slope.

Front

What type of slope does a vertical line have?

Back

Undefined slope.

Front

If a line has a slope of 7/5, how does it move?

Back

It moves up 7 units for every 5 units it runs to the right.

Front

What is the slope of a line that runs 4 units to the right and falls 2 units?

Back

-2/4 or -1/2.

Front

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

Back

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