This math topic focuses on identifying the slope of both vertical and horizontal lines given in equation form. The problems present line equations like "y = constant" and "x = constant," and students choose the correct slope value from multiple choices. The topic aims to help learners understand the characteristics of vertical lines (undefined or infinite slope) and horizontal lines (zero slope). This is a fundamental exercise in the broader unit of line equations and graphing.
