You would write your 2 ordered pairs based on the year and the amount of yogurt sold in that year.
The x-value (your first number in the ordered pair) the year and the y-value (the 2nd number in the ordered pair) the amount of yogurt.
(2002, 2133) and (2007, 3478) would be your 2 ordered pairs.
The answer is (4,5) (5,-5) (6,-4) (7,3) (8,1).
4 dirhams is equal to 1 dollar so if you were to multiply each by 5 you would have 20 dirhams equaling 5 dollars
(1, -6) and (-5, 2)
Distance between 1 and -5 = 6
Distance between -6 and 2 = 8
6²+8²=x² (PYTHAGOREAN THEOREM)
36+64=x²
x² = 100
x = 10
Note: Not -10 because <em>distance cannot be negative.</em>
