The required arrangements of tables is
Table 2 < Table 1 < Table 3 < Table 5 < Table 4 < table 7 < Table 6
Step-by-step explanation:
Formula for unit rate :
From the given graph it is clear that the line passes through the points (0,0) and (11,20). So, unit rat of graph is
Similarly, we need to calculate the unit rate for each table.
Except table 2, all tables have greater unit rate than the graph.
The required arrangement of tables is
Table 2 < Table 1 < Table 3 < Table 5 < Table 4 < Table 7 < Table 6
You literally need to apply the formula
