Slope from a Graph

Front

What is the definition of slope?

Back

The slope is a measure of the steepness or incline of a line, calculated as the ratio of the vertical change to the horizontal change between two points on the line.

Front

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

Back

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

Front

What is the slope of a line that rises from left to right?

Back

Positive slope.

Front

What is the slope of a line that falls from left to right?

Back

Negative slope.

Front

What is the slope of a horizontal line?

Back

Zero slope.

Front

What is the slope of a vertical line?

Back

Undefined slope.

Front

If a line has a slope of 4/3, what does this indicate about the line's steepness?

Back

The line rises 4 units for every 3 units it moves to the right, indicating a relatively steep incline.

Front

Identify the type of slope: A line that has a slope of -5/3.

Back

Front

Identify the type of slope: A line that has a slope of 0.

Back

Zero slope.

Front

Identify the type of slope: A line that has a slope of 3/5.

Back

Positive slope.
