Front

What is the definition of function?

Back

Every input has only ONE output.

Front

Front

What is a linear function?

A function that graphs to a straight line.

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 find the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does it mean for a function to be one-to-one?

Back

Each output is paired with exactly one input.
