Solve the Problem. -Suppose That During a Certain Step in a Chemical Manufacturing

Solve the problem.
-Suppose that during a certain step in a chemical manufacturing process the amount of chlorine dissolved in a solution, measured in parts per million (ppm) , is related to the elapsed time measured from the beginning of the step. Use the following table as a representation of this relationship. Write the data from the table as ordered pairs (x, y) , where x represents the time and y represents the amount dissolved.

A) (1, 18.0) , (2, 20.4) , (3, 22.4) , (4, 24.4) , (5, 26.2)
B) (18.0, 4) , (20.4, 8) , (22.4, 12) , (24.4, 16) , (26.2, 20)
C) (0, 18.0) , (4, 20.4) , (8, 22.4) , (12, 24.4) , (16, 26.2)
D) (4, 18.0) , (8, 20.4) , (12, 22.4) , (16, 24.4) , (20, 26.2)
