In 2D geometry, a point is a location on a plane, and a line is a set of points that extend infinitely in two directions. To measure the distance between a point and a line, we need to use a specific formula. Imagine a point (x1, y1) and a line with an equation y = mx + b, where m is the slope and b is the y-intercept. The distance between the point and the line can be calculated using the formula:

A: The formula for measuring the distance between a point (x1, y1) and a line y = mx + b is d = |(y1 - (m * x1 - b))| / sqrt(m^2 + 1).
