Slope from a Graph, Two Points and a Table

Front

What is the definition of slope?

Back

The slope of a line is a measure of its steepness, usually represented as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.

Front

How do you determine if a slope is positive, negative, zero, or undefined?

Back

A slope is positive if the line rises from left to right, negative if it falls from left to right, zero if it is horizontal, and undefined if it is vertical.

Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

Front

Find the slope of the line that passes through the points (1, 2) and (3, 6).

Back

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal and there is no vertical change as you move along the line.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical, meaning there is no horizontal change as you move along the line.

Front

If a line has a negative slope, what does this tell you about the direction of the line?

Back

A negative slope indicates that the line falls as it moves from left to right.

Front

Calculate the slope of the line that passes through the points (2, 4) and (6, 12).

Back

Front

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

Back

The slope of a perfectly vertical line is undefined.

Front

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

Back

The slope of a perfectly horizontal line is 0.
