If Jackson saves up some money to buy a new phone, you can determine how much he has in his bank account based on the number of weeks and this can also be plotted on a graph.
First the variables are x and y, where x is the number of week and y is the total amount in his bank account at x weeks. Therefore, if he saves $50 per week, then the table of values would appear as follows;
[x = 1, y = 50] [x = 2, y = 100] [x = 3, y = 150] [x = 4, y = 200] [x = 5, y = 250]
[x = 6, y = 300] [x = 7, y = 350] [x = 8, y = 400] [x = 9, y = 450] [x = 10, y = 500].
