This math topic focuses on the ability to find specific points on the graph of a linear equation. It falls under the broader unit of line equations and graphing practice, emphasizing the student's skill in substituting a given x-value into a linear equation to calculate the corresponding y-value and determining the coordinate point. The problems involve simple linear equations of the form y = mx + b, where students are challenged to find the y-coordinate when the x-coordinate is provided, enhancing their grasp of how linear equations are graphically represented and interpreted.
