Slope of Lines Flashcard

Front

What does a horizontal line on a graph represent?

Back

Constant speed (slope = 0)

Front

What does a vertical line on a graph represent?

Back

Undefined slope (not a function)

Front

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

Back

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

Front

What does a positive slope indicate about a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

The line falls from left to right.

Front

What is the slope of a line that is perfectly vertical?

Back

Undefined

Front

What is the slope of a line that is perfectly horizontal?

Back

0

Front

If a line has a slope of 3/2, what does this mean?

Back

For every 2 units moved horizontally, the line moves up 3 units.

Front

What does it mean if the slope of a line is 0?

Back

The line is horizontal and represents constant speed.

Front

How do you determine the slope from a graph?

Back

Choose two points on the line and use the slope formula.
