Back

A relation where each input has exactly one output.

Front

What is the y-intercept of a linear equation?

Back

The point where the line crosses the y-axis.

Front

How do you find the slope of a line given two points?

Back

Slope (m) = (y2 - y1) / (x2 - x1) for points (x1, y1) and (x2, y2).

Front
