standard_description: Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.)
problem_activity: Coordinates for points are shown in the table.
|          Point           | Coordinate |
|--------------------------|------------|
| *           W          * |   (2, 3)   |
| *           X          * |   (4, 0)   |
| *           Y          * |   (5, 2)   |
| *           Z          * |   (0, 1)   |
Graph all the points from the table in the coordinate grid. Label them with their corresponding letters.
