The slope of a line is calculated as the change in the vertical axis divided by the change in the horizontal axis. Between income levels of 50 and 200, if we assume the vertical change corresponds to a typical economic or financial metric (e.g., tax, benefit, etc.), the exact values at these points are not provided, but the method to find the slope remains the same. Assuming a linear relationship and given points (50, y1) and (200, y2), the slope (m) is calculated as m = (y2 - y1) / (200 - 50). Without specific y-values, the correct answer cannot be directly calculated from the information provided; however, the choice of "5" as the correct answer suggests a specific context or a standard example where the change in the vertical axis over the change in the horizontal axis (150) equals 5. This could imply that for every increase of 150 in income, the corresponding metric increases by 750 (150 * 5), but without specific values or context, this explanation relies on understanding that the slope calculation is the ratio of the change in the dependent variable to the change in the independent variable.
