Back

A function is a relation that assigns exactly one output for each input.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run.

Front

Back

The y-intercept is the point where the line crosses the y-axis.

Front

How do you determine if a relation is a function?

Back

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

Front

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

Back

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