Identifying Types of Slope

Front

What is slope?

Back

Slope is a measure of the steepness or incline of a line, typically represented as the ratio of the vertical change to the horizontal change between two points on the line.

Front

What type of slope is represented by a line that goes upwards from left to right?

Back

Positive slope.

Front

What type of slope is represented by a line that goes downwards from left to right?

Back

Negative slope.

Front

What type of slope is represented by a horizontal line?

Back

Zero slope.

Front

What type of slope is represented by a vertical line?

Back

Undefined slope.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

The line is horizontal and does not rise or fall.

Front

If a line has a negative slope, what does that indicate about the line's direction?

Back

The line decreases in value as it moves from left to right.

Front

How can you determine if a slope is positive or negative from a graph?

Back

If the line rises from left to right, it is positive; if it falls from left to right, it is negative.

Front

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

Back

Undefined slope.

Front

What does a slope of 1 indicate?

Back

For every unit increase in the x-direction, there is a one unit increase in the y-direction, resulting in a 45-degree angle.
