Front

Define an explicit formula for a sequence.

Back

An explicit formula defines the nth term of a sequence as a function of n.

Front

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

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you determine if a line is solid or dashed in inequalities?

Back

A solid line indicates 'greater than or equal to' or 'less than or equal to'; a dashed line indicates 'greater than' or 'less than'.

Front

What does the term 'sequence' mean in mathematics?

Back

A sequence is an ordered list of numbers that follow a specific pattern.

Front

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

Back

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