The line passes through (0, 0) and (4, -4), slanting downward from left to right. Its slope is Rise / Run = (-4 – 0) / (4 – 0) = -4 / 4 = -1.

The line passes through the origin (0, 0) and the marked grid point (4, -4). As it moves from left to right, it slants downwards, indicating a negative slope. Using the two-point formula, slope = (y₂ – y₁) / (x₂ – x₁) = (-4 – 0) / (4 – 0) = -4 / 4 = -1. Hence, the slope of line l is -1.
