What is the definition of slope?

Back

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

Front

What does a vertical slope indicate?

Back

A vertical slope indicates that the line is undefined and does not have a slope value.

Front

What is the common difference in an arithmetic sequence?

Back

The common difference is the constant amount that each term in the sequence increases or decreases by.

Front

How do you find the slope of a line perpendicular to another line?

Back

To find the slope of a line perpendicular to another, take the negative reciprocal of the slope of the original line.

Front

What is the formula for solving for a in terms of p and w?

Back

The formula is a = p/w.

Front

What is a function?

Back

A function is a relation where each input has exactly one output.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you determine if a relation is a function?

Back

A relation is a function if every input (x-value) corresponds to exactly one output (y-value).

Front

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

Back

The formula for slope is m = (y2 - y1) / (x2 - x1).

Front

What is the significance of a slope of zero?

Back

A slope of zero indicates a horizontal line, meaning there is no vertical change as x changes.
