Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

Front

What does it mean for two lines to be parallel?

Back

They never intersect and have the same slope.

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.
