Explanation:

An ordered pair is written in the form (x, y), where x is the independent variable (hours spent studying) and y is the dependent variable (quiz score). Looking at the table, for each row, the first value is hours spent studying (x) and the second is quiz score (y).

Answer:

B. (0.50,10),(0.75,11),(1.00,12),(1.25,14),(1.50,15),(1.75,15),(1.75,18),(2.00,20)
