In Algebra `1`, the worksheets in the coordinate plane unit help students learn important skills for graphing and understanding points, lines, and shapes on a flat surface with `x` and `y` axes. These worksheets teach students how to plot points accurately, figure out where points are on a graph, find the middle point between two given points, determine where a point is when you know the middle point and another point, and calculate how far apart two points are. By practicing these exercises, students become skilled in using the coordinate plane to solve problems.
