Question

mrs. robertson is preparing manipulatives for her math class. each student will receive a plastic cup with 20 two-color counters. the total number of two-color counters, \\(c\\), that mrs. robertson needs varies directly as the number of students, \\(s\\).

draw a graph showing the proportional relationship between \\(c\\) and \\(s\\).

Answer:

The proportional relationship is represented by the direct variation equation:

$$c = 20s$$

To draw the graph, plot a line starting at the origin \((0, 0)\) and passing through the point \((10, 200)\) or \((20, 400)\).
