This math topic focuses on using the Cartesian grid to calculate the unknown coordinate of a point when the other coordinate and the line's length are given. It practices geometric reasoning, specifically involving the distance formula on a Cartesian coordinate system for lines with positive coordinate values only. Students are asked to identify missing x or y coordinates to ensure the line segment connecting two points has a specified length. The problems are provided at a level that likely assumes prior knowledge of concepts related to distances on the Cartesian grid.
