Coordinate Graphing
-
Problems in which pre-algebra students learning about the x- and y- coordinates and the coordinate plane in general.
For problems about graphing on the coordinate plane which focus on the equation of the line, the
problem would be found under Algebra: Linear Relationships. If the
reason for graphing is to analyze data, the appropriate category would be Statistics.
