In the coordinate plane, consider point P at coordinates (4, 6) and point Q at coordinates (8, 10).
What is the slope of the line that passes through points P and Q?
Recall that the formula for the slope (m) between two points (x1, y1) and (x2, y2) is given by:
$$ m = \frac{y_2 - y_1}{x_2 - x_1} $$
