This math topic focuses on understanding the Y coordinate within a Cartesian grid, specifically without indicators for what the values represent. Questions challenge students to identify whether a particular number given in a coordinate pair (point) represents an X or Y value and whether it is positive or negative. Multiple-choice answers accompany each question, requiring students to discern among options that describe the coordinate value correctly. This topic is part of a foundational course on Cartesian grids.
