Slope Calculation in Coordinate Geometry

Consider the points A(2, 1) and B(6, 5) in the coordinate plane. What is the slope of the line that passes through points A and B?

Recall that the slope of a line passing through two points $(x_1, y_1)$ and $(x_2, y_2)$ can be calculated using the formula:

$$ m = \f\frac{y_2 - y_1}{x_2 - x_1} $$
