Front

What does the slope of a line indicate?

Back

The slope indicates the steepness and direction of the line; a positive slope rises from left to right, while a negative slope falls.

Front

What is the y-intercept?

Back

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

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

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