To find the point that represents Sidaanth's savings on the graph, we need to plot the pairs of values from his chart.

The relationship between weeks and savings is as follows:

  • At week 1, savings = $7.00
  • At week 2, savings = $14.00
  • At week 3, savings = $21.00
  • At week 4, savings = $28.00

This means the points would be (1, 7), (2, 14), (3, 21), and (4, 28).

Now looking at the options:

  • Point A is (1, 28) - incorrect
  • Point B is (2, 14) - correct (because savings at week 2 is $14)
  • Point C is (7, 2) - incorrect
  • Point D is (14, 1) - incorrect

The correct point that represents this relationship is Point B (2, 14).
