The slope of a line is calculated by the change in the vertical axis divided by the change in the horizontal axis. Without specific values for the vertical axis, we assume it represents some form of output or productivity. If we denote the output at 20 hours as Y1 and at 30 hours as Y2, the slope formula is (Y2 - Y1) / (30 - 20). Without specific Y values, we can't calculate an exact number, but the correct answer choice B, 5, suggests a general understanding of how to calculate slope rather than a specific numerical answer.
