Back

Slope represents the steepness of a line, indicating how much y changes for a change in x.

Front

What is the formula for calculating slope?

Back

The formula for calculating slope (m) is m = (y2 - y1) / (x2 - x1).

Front

What is a vertical line's equation format?

Back

A vertical line's equation is in the format x = a, where 'a' is a constant.

Front
